Pirated Movie Release Formats 如何区分影片质量



Nobody can say that they have never seen or downloaded pirated movies, actually one of the Internet's main use is to watch pirated movies. In recent times the pirated Version of the  movies are available on the Internet on the same day of the movie release. But before downloading pirated movies you have to check release format. If you don't have the knowledge of the pirated movie formats you would be left with a bad copy of the film when other better prints were available for download. So i thought about writing about the popular pirated movie formats. Mostly the information is taken from wikipedia but i have also included my own opinions and experiences of the formats so if you want you can take a look at the wikipedia article. So here are the different formats arranged mostly in the sequence of their releases time.

Type:- CAM
Label :- CAMRip or CAM
Mostly CAM version of the movies appear online on the same day of the movie release. CAM copies of the movies are made by recording the movie using a camcorder in the theaters. Due to this, the print quality depends upon the quality of the camcorder. The sound quality too is not that good as it is recorded by the camcorder.
Note:- If you are in a real hurry to watch the movie and the only available version is a CAM, then try to download the movie from good site uploaded by popular warez groups like FXG, aXXo, Devise etc. If downloading from torrent please read the comments, you can get a fairly good idea of the print by reading the comments.

Type:- Telesync
Label:- TS or PreDVD
TS versions are CAM versions with a better audio from a secondary source.
PreDVD are rips of pirated DVD sold on the roadside. The actually are CAM versions, maybe of higher quality.
Note:- If you have waited for a TS and PreDVD copy i would suggest to wait a couple of days more for better quality prints.

Type:- Pay-Per-View Rip
Label:- PPVRip
These are rips of the moveis from the Pay per view sources .The are good quality prints and with good sound. Recently this prints have become very common.

Type:- Screener
Label :- DVDScr
These are the rips of the DVD and BR of the movie sent to the reviewers and other peoples for the purpose of reviewing the movie. Mostly the copies have watermarks or message. Some times some of the film sequences are in Black and White.

Type:- Region 5
Label:- R5
R5 are rip of the DVD of the movies available in the region 5 which consist of the Indian subcontinent, Africa, North Korea, Russia and Mongolia.
Note:- It is suggested that the audio quality of the R5 prints is not that good because the audio is synced later from some secondary source. But my experience with R5 rips has been good and i was not able to find many difference between the audio, so i would suggest its OK to download R5 rips.

Type:- HDTV or DS rip
Label:- HDTV, TVrip or DTHrip
This are rips captured from the analog or DTH sources.

Type:- DVD and Blu-Ray rips
Label:- DVDrip and BDrips
These are the best quality rips as the are ripped from the official DVD and Blu-Rays of the movie.
Note:- In recent times the DVD and Blu-Rays appear online very quickly so if you are not in a great hurry to see the movie, i would suggest to wait for this version of the movie.

There are some more version but his are the most popular and common and i would suggest you to stick with this versions.

经常会和朋友们分享最新上架的电影,在分享电影的时候,就会涉及到一些常见的视频专业名词,一般不容易理解,且很难却分什么样的影片质量好,什么样的影片质量差。下面就常见的TS、TC、CAM、SCR、DVDRip、DVDScr、VHSRip、TVRip、DivXRe-Enc、RMVB、SUBBED给予详细解释!

CAM
        通常是用数码摄像机从电影院盗录。有时会使用小三角架,但大多数时候不可能使用,所以摄像机会抖动。同时由于放摄像机的座位并非总是空的,使得有时拍摄不是水平的。如果后期剪裁很好,这很难看出,除非屏幕下方有字幕。由于声音是从摄像机自带的话筒录制,所以经常会录到观众的笑声等声音,尤其是喜剧片。因为这些因素,图象和声音质量通常都很差。但有时很幸运电影院相当空,这样会录到好一些的声音。

TS (TELESYNC)
     除了使用外置的音源(一般是影院座椅上为听力不好的人设的耳机孔),TELESYSNC(TS) 和CAM的标准是相同的。这个直接的音源并不能保证是好的音源,这是它因为受到很多背景噪音的干扰。很多时候TS是在空的影院录制,或是用专业摄像机在投影室录制,所以图象质量可能比CAM好。质量的起伏可能很大,在下载前最好查看SAMPLE。很大比例的TS是从CAM错误标记成。

TC (TELECINE)
     使用电视电影机从胶片直接数字拷贝,其图象和声音质量应该很好。但由于使用的设备和费用很高,TC很少见。通常会使用正确的高宽比,但有时也有4:3的TC。去年的侏罗纪公园III是一个很好的例子。不应将TC和TimeCode(时间码)混淆,时间码是一个在屏幕上可见的计数器。

 SCR(SCREENER)
     SCREENER(SCR)是在电影发行VHS录象带之前送到录象出租店及其他地方用做促销目的。SCREENER使用VHS录象带,通常使用4:3(全屏)的高宽比,但有时也会有LETTERBOXED(1.85:1宽银幕) SCREENER. 主要的缺点是有“TICKER”(在屏幕下方滚动的消息,包含版权和反盗版电话号码)。同时,如果录象带包含任何序列号或可以导致查出录象带来源的记号,这些记号必须被遮掉,通常使用一个黑斑遮住上述部位。有时这些记号只出现几秒钟,有时也可能不幸在怎个电影中出现,而且有时会很大。根据使用的设备,SCREENER的质量可能是极好,如果是从原版拷贝;也可能很差,如果是从翻录的拷贝录制,同时又使用很烂的捕捉设备和录象机。大多数的SCREENER被转制成VCD,现在也出现了SVCD;有些看起来比另一些好。

DVDscr(DVD-SCREENER) 
     DVD-SCREENER(DVDscr)和SCREENER相似,但是从DVD转制。通常是1.85:1宽银幕,但是不包括零售版会有的花絮。TICKER经常不在黑边里,所以会影响观看。如果转制者稍有技术,DVDScr应该很好。通常被转制成SVCD或DivX/XviD。

DVDRip
    DVDRip是从最终版的DVD转制。如果可能,应该是使用预售版(比如,星球大战2)。质量应该很好。通常被发布成SVCD或DivX/XviD

VHSRip
VHSRip是从零售版VHS录象带转制,主要是滑冰/体育内容和XXX发布。

TVRip
    从电视(最好是从数码有线电视/卫星电视捕捉)转制的电视剧,或接收由卫星提前几天向电视网传送的预播节目(不包含加密但有时有雪花)。有些节目,比如WWF RAW IS WAR包含多余的部分;”DARK MATCHES”和CAMERA/COMMENTARY测试被包含在TVRip里。PDTV是从PCI数码电视卡捕捉,通常效果最好;破解组织倾向于使用SVCD来发布。VCD/SVCD/DivX/XviD rips也都被用于发布TVRip。

DivXRe-Enc
    DivXRe-Enc是从原始VCD发布用DivX编码成的小一些的文件。通常可在文件共享网络找到。它们通常以Film.Name.Group(1of2)等形式命名。常见的发布组织有SMR和TND。这些版本通常不值得下载,除非你不清楚某部电影,只想要200MB的版本。一般应避免。

SUBBED
    对于VCD发布而言,SUBBED通常表示字幕被压进了电影。它们通常是马来语/中文/泰文等,有时有两种语言。它们可能占据了很大一部分屏幕。SVCD支持外挂字幕,所以DVDRip用外挂字幕发布。这些信息可以在NFO文件中找到。

RMVB
   在大部分的BT网站上,我们见的更多的是rmvb格式的,一般在文件名上都会出现***-rmvb,例如:DVDRip-RMVB,这个表示电影文件是由DVDRip版本压缩成RMVB的。这种格式占用容量一般小得多,并且内嵌字幕,但是效果要降低的很多。

另,关于电影的其他参数:
PROPER:完整版
UNARATE:未删节
R_RATEE:有删节
WS:表示宽银幕
FS:表示全屏幕
WITH EXTRAS:影片带花絮

How to Enable/Load Two or More External Hard Drives on Windows 7 (Identical Signatures - Same Brand, Manufacture, Size)

Cause:
This issue is caused by the two drives having identical signatures, leading to a Signature Collision. This is different from the drive's serial number, which is always unique.

Solution 1: 

Normally the Operating System (OS) (Such as Windows XP and Windows Vista) will automatically correct the issue when the second drive is connected. However, in Windows 7, this does not occur. When using Windows 7, please follow the steps below to give one of the drives a new unique signature.

Critical: Follow these steps carefully. Improper use of Windows Disk Managment tool can result in permanent loss of data.



1. Connect each drive (one at a time) and create a backup of any data you may already have stored on the device.
2. Connect both drives to the computer.
3. Open the Start Menu, type diskmgmt.msc and press Enter.


4. On the lower part of the Disk Management window, look for a disk which is listed as Offline.
5. Verify that you have a Signature Collision by holding your mouse over the drive. You will receive a pop-up explaining why the drive is offline.


6. Right click on the disk in the area that says Offline, and select Online
7. The drive will be given a new signature. A new Drive Letter should appear and you should now be able to access the drive. 

OR 

1. Go to Computer Management --> Disk Management 
2. Check the status of the drive that is plugged in but Windows 7 is not recognizing. 

You may notice that is offline with a notice that reads as follows: 
"The disk is offline because it has a signature collusion with another disk that is online." 

3. Simply right-click the offline disk and click 'online.' 
Problem should be solved! 


Solution 2: 

1. Go to Start Menu 
2. Type Computer Management
3. When this opens, select Storage then Disk Management
4. Find the USB disk you are interested in. 
5. Right Click on the partition, select Change Drive Letter and Path... 
6. Pick an available letter. 
7. Repeat steps 4 to 6 for each disk/partition. 


Solution 3: 

01. Plug in and turn on the external USB hard drive 
02. Right click on My Computer 
03. Left click on Manage 
04. Left click on Device Manager 
05. Expand the USB list 
06. Find the USB device for your USB Hard Drive (in my case it was the one that had no description) 
07. Right click - Uninstall 
08. Turn off the external USB hard drive 
09. Turn on the external USB hard drive and let it find and install the driver 
10. It should work

Using Google Public DNS


Download this page in PDF 

Configuring your network settings to use Google Public DNS

When you use Google Public DNS, you are changing your DNS "switchboard" operator from your ISP to Google Public DNS.
In most cases, the IP addresses used by your ISP's domain name servers are automatically set by your ISP via the Dynamic Host Configuration Protocol (DHCP). To use Google Public DNS, you need to explicitly change the DNS settings in your operating system or device to use the Google Public DNS IP addresses. The procedure for changing your DNS settings varies according to operating system and version (Windows, Mac or Linux) or the device (computer, phone, or router). We give general procedures here that might not apply for your OS or device; please consult your vendor documentation for authoritative information.
Note: We recommend that only users who are proficient with configuring operating system settings make these changes.

Important: Before you start

Before you change your DNS settings to use Google Public DNS, be sure to write down the current server addresses or settings on a piece of paper. It is very important that you keep these numbers for backup purposes, in case you need to revert to them at any time.
After changing your settings, if you encounter a problem and cannot connect to the Internet, please call our support numbers for troubleshooting instructions.
We also recommend that you download this page and print it, in the event that you encounter a problem and need to refer to these instructions.

Google Public DNS telephone support

  • 877-590-4367 in the U.S.
  • 770-200-1201 outside the U.S.

Google Public DNS IP addresses

The Google Public DNS IP addresses (IPv4) are as follows:
  • 8.8.8.8
  • 8.8.4.4
The Google Public DNS IPv6 addresses are as follows:
  • 2001:4860:4860::8888
  • 2001:4860:4860::8844
You can use either number as your primary or secondary DNS server. You can specify both numbers, but do not specify one number as both primary and secondary.
You can configure Google Public DNS addresses for either IPv4 or IPv6 connections, or both.

Changing your DNS servers settings

Because the instructions differ between different versions/releases of each operating system, we only give one version as an example. If you need specific instructions for your operating system/version, please consult your vendor's documentation. You may also find answers on our user group.
Many systems allow you to specify multiple DNS servers, to be contacted in a priority order. In the following instructions, we provide steps to specify only the Google Public DNS servers as the primary and secondary servers, to ensure that your setup will correctly use Google Public DNS in all cases.
Note: Depending on your network setup, you may need administrator/root privileges to change these settings.

Microsoft Windows

DNS settings are specified in the TCP/IP Properties window for the selected network connection. 
Example: Changing DNS server settings on Microsoft Windows 7
  1. Go the Control Panel.
  2. Click Network and Internet, then Network and Sharing Center, and click Change adapter settings.
  3. Select the connection for which you want to configure Google Public DNS. For example:
    • To change the settings for an Ethernet connection, right-click Local Area Connection, and click Properties.
    • To change the settings for a wireless connection, right-click Wireless Network Connection, and click Properties.
    If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
  4. Select the Networking tab. Under This connection uses the following items, select Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6) and then click Properties.
  5. Click Advanced and select the DNS tab. If there are any DNS server IP addresses listed there, write them down for future reference, and remove them from this window.
  6. Click OK.
  7. Select Use the following DNS server addresses. If there are any IP addresses listed in the Preferred DNS server or Alternate DNS server, write them down for future reference.
  8. Replace those addresses with the IP addresses of the Google DNS servers:
    • For IPv4: 8.8.8.8 and/or 8.8.4.4.
    • For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844
  9. Restart the connection you selected in step 3.
  10. Test that your setup is working correctly; see Testing your new settings below.
  11. Repeat the procedure for additional network connections you want to change.

Mac OS X

DNS settings are specified in the Network window. 
Example: Changing DNS server settings on Mac OS 10.5
  1. From the Apple menu, click System Preferences, then click Network
  2. If the lock icon in the lower left-hand corner of the window is locked, click the icon to make changes, and when prompted to authenticate, enter your password.
  3. Select the connection for which you want to configure Google Public DNS. For example:
    • To change the settings for an Ethernet connection, select Built-In Ethernet, and click Advanced.
    • To change the settings for a wireless connection, select Airport, and click Advanced.
  4. Select the DNS tab.
  5. Click + to replace any listed addresses with, or add, the Google IP addresses at the top of the list:
    • For IPv4: 8.8.8.8 and/or 8.8.4.4.
    • For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844
  6. Click Apply and OK.
  7. Test that your setup is working correctly; see Testing your new settings below.
  8. Repeat the procedure for additional network connections you want to change.

    Linux

    In most modern Linux distributions, DNS settings are configured through Network Manager.
    Example: Changing DNS server settings on Ubuntu
    1. In the System menu, click Preferences, then click Network Connections.
    2. Select the connection for which you want to configure Google Public DNS. For example:
      • To change the settings for an Ethernet connection, select the Wired tab, then select your network interface in the list. It is usually called eth0.
      • To change the settings for a wireless connection, select the Wireless tab, then select the appropriate wireless network.
    3. Click Edit, and in the window that appears, select the IPv4 Settings or IPv6 Settings tab.
    4. If the selected method is Automatic (DHCP), open the dropdown and select Automatic (DHCP) addresses only instead. If the method is set to something else, do not change it.
    5. In the DNS servers field, enter the Google Public DNS IP addresses, separated by a space:
      • For IPv4: 8.8.8.8 and/or 8.8.4.4.
      • For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844
    6. Click Apply to save the change. If you are prompted for a password or confirmation, type the password or provide confirmation.
    7. Test that your setup is working correctly; see Testing your new settings below.
    8. Repeat the procedure for additional network connections you want to change.
    If your distribution doesn't use Network Manager, your DNS settings are specified in /etc/resolv.conf.
    Example: Changing DNS server settings on a Debian server
    1. Edit /etc/resolv.conf:
      sudo vi /etc/resolv.conf
    2. If any nameserver lines appear, write down the IP addresses for future reference.
    3. Replace the nameserver lines with, or add, the following lines:
      For IPv4:
      nameserver 8.8.8.8
      nameserver 8.8.4.4
      For IPv6:
      nameserver 2001:4860:4860::8888
      nameserver 2001:4860:4860::8844
    4. Save and exit.
    5. Restart any Internet clients you are using.
    6. Test that your setup is working correctly; see Testing your new settings below.
    Additionally, if you are using DHCP client software that overwrites the settings in /etc/resolv.conf, you will need to set up the client accordingly by editing the client's configuration file.
    Example: Configuring DHCP client sofware on a Debian server
    1. Back up /etc/resolv.conf:
      sudo cp /etc/resolv.conf /etc/resolv.conf.auto
    2. Edit /etc/dhcp3/dhclient.conf:
      sudo vi /etc/dhcp3/dhclient.conf
    3. If there is a line containing domain-name-servers, write down the IP addresses for future reference.
    4. Replace that line with, or add, the following line:
      For IPv4:
      prepend domain-name-servers 8.8.8.8, 8.8.4.4;
      For IPv6:
      prepend domain-name-servers 2001:4860:4860::8888, 2001:4860:4860::8844;
    5. Save and exit.
    6. Restart any Internet clients you are using.
    7. Test that your setup is working correctly; see Testing your new settings below.

    Routers

    Every router uses a different user interface for configuring DNS server settings; we provide only a generic procedure below. For more information, please consult your router documentation.
    Note: Some ISPs hard-code their DNS servers into the equipment they provide; if you are using such a device, you will not be able to configure it to use Google Public DNS. Instead, you can configure each of the computers connected to the router, as described above.
    To change your settings on a router:
    1. In your browser, enter the IP address to access the router's administration console. 
    2. When prompted, enter the password to access network settings.
    3. Find the screen in which DNS server settings are specified. 
    4. If there are IP addresses specified in the fields for the primary and seconday DNS servers, write them down for future reference.
    5. Replace those addresses with the Google IP addresses:
      • For IPv4: 8.8.8.8 and/or 8.8.4.4.
      • For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844
    6. Save and exit.
    7. Restart your browser.
    8. Test that your setup is working correctly; see Testing your new settings below.

    Mobile or other devices

    DNS servers are typically specified under advanced wi-fi settings. However, as every mobile device uses a different user interface for configuring DNS server settings, we provide only a generic procedure below. For more information, please consult your mobile provider's documentation.
    To change your settings on a mobile device:
    1. Go to the screen in which wi-fi settings are specified.
    2. Find the screen in which DNS server settings are specified.
    3. If there are IP addresses specified in the fields for the primary and seconday DNS servers, write them down for future reference.
    4. Replace those addresses with the Google IP addresses:
      • For IPv4: 8.8.8.8 and/or 8.8.4.4.
      • For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844
    5. Save and exit.
    6. Test that your setup is working correctly; see Testing your new settings below.

    Testing your new settings

    To test that the Google DNS resolver is working:
    1. From your browser, type in a hostname (such as http://www.google.com/). If it resolves correctly, bookmark the page, and try accessing the page from the bookmark. If both of these tests work, everything is working correctly. If not, go to step 2.
    2. From your browser, type in a fixed IP address. You can use http://18.62.0.96/ (which points to the website http://www.eecs.mit.edu/) as the URL*. If this works correctly, bookmark the page, and try accessing the page from the bookmark. If these tests work (but step 1 fails), then there is a problem with your DNS configuration; check the steps above to make sure you have configured everything correctly. If these tests do not work, go to step 3.
    3. Roll back the DNS changes you made and run the tests again. If the tests still do not work, then there is a problem with your network settings; contact your ISP or network administrator for assistance.
    * Google thanks MIT for granting permission to use this URL for the purposes of testing web connectivity.

    Diagnosing resolution problems

    If you are encountering problems when resolving particular names, and want to verify whether the problem is with Google Public DNS, please try running the following diagnostic procedures. If you want to report a problem to the Google Public DNS user group, please copy and paste the results of the commands in your email. This information is vital to help us to identify the cause of the problem.

    Step 1: Verify that your client can communicate with the Google Public DNS servers

    IPv4

    Open a command prompt, and run the following command:
    On Windows:
    tracert -d 8.8.8.8
    On Mac OS X:
    /usr/sbin/traceroute -n -w 2 -q 2 -m 30 8.8.8.8
    On Linux:
    sudo traceroute -n -w 2 -q 2 -m 30 8.8.8.8
    If the last line of the output does not list 8.8.8.8 as the final hop, or if there are significant timeouts, there may be a network problem preventing you from contacting our servers. Please include the output of the command in any communication with the Google Public DNS team.
    If the last line of the output does list 8.8.8.8 as the final hop, continue to step 2.

    IPv6

    Open a command prompt, and run the following command:
    On Windows:
    tracert -d 2001:4860:4860::8888
    On Mac OS X:
    /usr/sbin/traceroute -n -w 2 -q 2 -m 30 2001:4860:4860::8888
    On Linux:
    sudo traceroute -n -w 2 -q 2 -m 30 2001:4860:4860::8888
    If the last line of the output does not list 2001:4860:4860::8888 as the final hop, or if there are significant timeouts, there may be a network problem preventing you from contacting our servers. Try configuring Google Public DNS for IPv4 to diagnose whether the problem is due to IPv6 connectivity on your network. If IPv4 works for you, you may want to revert your IPv6 configuration and use Google Public DNS with IPv4 exclusively. Otherwise, please include the output of the command in any communication with the Google Public DNS team.
    If the last line of the output does list 2001:4860:4860::8888 as the final hop, continue to step 2.

    Step 2: Verify that Google Public DNS can resolve the selected hostname

    IPv4

    At the command prompt, run the following command, replacing www.google.com. with the name that you were having difficulty resolving (putting a period at the end of the name to avoid problems with domain suffixes and search lists):
    On Windows:
    nslookup -debug www.google.com. 8.8.8.8
    On Mac and Linux:
    dig @8.8.8.8 www.google.com.
    If the output shows an answer section with an A record for the hostname, then Google Public DNS is able to resolve the name. Check your settings to make sure your system is correctly configured to use Google Public DNS. If you are still unable to solve the problem, please include the output of the command in any communication with the Google Public DNS team.
    If the output does not show an answer for the hostname, continue to step 3.

    IPv6

    Windows
    At the command prompt, run the following command, replacing www.google.com. with the name that you were having difficulty resolving* (putting a period at the end of the name to avoid problems with domain suffixes and search lists):
    nslookup -debug -type=AAAA www.google.com. 2001:4860:4860::8888
    If the output shows an answer section with an AAAA record for the hostname, then Google Public DNS is able to resolve the name. Check your settings to make sure your system is correctly configured to use Google Public DNS. If you are still unable to solve the problem, please include the output of the command in any communication with the Google Public DNS team.
    If the output shows an answer section with an A (IPv4) record for the hostname, then Google Public DNS is able to resolve the name, but the host and/or its nameserver are not configured to return IPv6 results. If you want to verify that you are correctly receiving AAAA records, you can use the hostnameipv6.google.com as a generic test.
    If the output for ipv6.google.com, or another host for which you are certain IPv6 records exist, does not show an answer, continue to step 3.
    On Mac and Linux
    At the command prompt, run the following command, replacing www.google.com. with the name that you were having difficulty resolving*. (putting a period at the end of the name to avoid problems with domain suffixes and search lists):
    dig @2001:4860:4860::8888 www.google.com. AAAA
    If the output shows an answer section with an AAAA record for the hostname, then Google Public DNS is able to resolve the name. Check your settings to make sure your system is correctly configured to use Google Public DNS. If you are still unable to solve the problem, please include the output of the command in any communication with the Google Public DNS team.
    If the output does not show an AAAA record for the hostname, this may be because the the host and/or its nameserver are not configured to return IPv6 results. If you want to verify that you are correctly receiving AAAA records, you can use the hostname ipv6.google.com as a generic test.
    If the output for ipv6.google.com, or another host for which you are certain IPv6 records exist, does not show an answer, continue to step 3.
    *Note: Google properties will not return AAAA records for all users. Please see the Google over IPv6 page for more information about whether your system qualifies.

    Step 3: Verify that another open resolver can resolve the selected hostname

    At the command prompt, run any one of the following commands, replacing www.google.com. with the name that you were having difficulty resolving (still putting a period at the end of the name to avoid problems with domain suffixes and search lists):
    nslookup www.google.com. 4.2.2.1
    nslookup www.google.com. 4.2.2.2
    nslookup www.google.com. 208.67.222.222
    nslookup www.google.com. 208.67.220.220
    (The first two commands test Level 3's DNS servers. The last two commands test OpenDNS' DNS servers.)
    If you are not able to get a successful result, this means that there is most likely a problem with the server you are trying to contact. Wait some time and try running the tests again. This may be a temporary problem on the server's side that will likely resolve itself eventually. If it does not, you should contact the owner of the server.
    If you do get a successful result, there may be a problem with Google Public DNS. Please include the output of this command and the one from step 2 in any communication with the Google Public DNS team.

    Step 4: Check to see if the authoritative nameservers are correct

    If Google Public DNS (or any open resolver) has trouble resolving a site, or returns inconsistent answers, sometimes it's because the authoritative nameservers are having trouble. There are various tools and sites to help you check this. Some users (and some Google Public DNS engineers) have found intoDNS to be very helpful. For example, if you're trying to resolve www.example.com, visit intodns.com and enter example.com (the domain for www.example.com), or visithttp://intodns.com/example.com directly.
    Google thanks the intoDNS staff for letting us link to them.

    Switching back to your old DNS settings

    If you had not previously configured any customized DNS servers, to switch back to your old settings, in the window in which you specified the Google IP addresses, select the option to enable obtaining DNS server addresses automatically, and/or delete the Google IP addresses. This will revert your settings to using your ISP's default servers.
    If you need to manually specify any addresses, use the procedures above to specify the old IP addresses.
    If necessary, restart your system.

    7 Best “New” Web Browsers With A Chance Against Chrome & Firefox


    new web browsersMany people swear by either Google Chrome orMozilla Firefox, but there are a myriad of other new web browsers that are definitely worth a look. Truly, neither Chrome nor Firefox are perfect. There are some features we would like to see built into Firefox (that meanwhile, we’ll just have to satisfy with addons), and others that we still wonder why Chrome hasn’t bothered to include such as RSS feed detection (which meanwhile can also be satisfied with an add-on).
    A lot of the following browsers ship with addons that you would otherwise have to obtain yourself, so they may make for a fresh breath of air.

    Chromium [Cross-Platform]

    Since Google Chrome is a fork of the open-source browser project, Chromium, anything that applies to Chromium can be applied to Google Chrome, while not everything that pertains to Chrome can be applied to Chromium.
    For instance, to illustrate the very first point, both Chromium and Google Chrome offerSearch Suggest, which presents you with a list of suggestions as you pause when you’re typing in your search query. An area where the two browsers differ is in crash reporting or usage statistics; by default, sending these reports is opt-in and disabled in Chromium. Chromium also comes without a PDF Viewer and Adobe Flash Player, but all is not lost since you can actually utilize any of the extensions in Chrome’s Web Store in Chromium.
    Acquiring this browser takes a bit more than just finding the Download section and clicking on the installer link. You can follow these instructions here or you can use the unofficial, portable version on SourceForge.

    Chromium-Based Browsers: SRWare Iron & RockMelt

    SRWare Iron [Cross-Platform]

    latest web browsers
    If you like Google Chrome’s speed, but are concerned with privacy, SRWare’s Iron web browser might be for you. Since Google Chrome and SRWare Iron are based on the open source Chromium project, you’ll spot few differences. On the internal side of course, Iron doesn’t include Chrome’s information-collecting features, such as URL-tracker, error reporting, etc. Aside from those internal differences, Iron works pretty much the way you’re used to in Chrome. Chrome extensions and themes will also work on Iron, just like Chromium.
    To check out the portable version and the regular install in Windows, head to the website. Mac users can download Iron here, while Linux users can go to this thread.

    RockMelt 2 [Windows + Mac] + iPhone Sync

    latest web browsers
    If you’re big on sharing interesting news on Facebook, Twitter and/or email, RockMelt (in beta) might be worth a look. It’s similar to Flock, the social browser derived from Mozilla Firefox, in that it targets the die-hard social media addict so it integrates notifications from sites like Facebook and Twitter. It comes with a few tricks of its own though, the iPhone app [iTunes link], which syncs your items marked to read later, as well as bookmarks.
    latest web browsers
    Though RockMelt doesn’t support Google Sync, you can sync your RockMelt browsers across PCs and Macs with your Facebook account.

    Wyzo 3 [Windows + Mac]

    what new web browsers are there
    A few things have changed since we last reviewed Mozilla-based Wyzo, but it remains the most useful browser for the frequent downloader since it comes with FireDownload, a download accelerator, and FireTorrent, an extension that turns this browser into a torrent client. One new feature in Wyzo 3 is the inclusion of SkipScreen, the extension that allows you to skip waiting screens from popular file-sharing sites, such as MegaUpload and the like, while it no longer seems to ship with CoolIris and FireGestures.

    Maxthon 3.0 [Windows/Android]

    what new web browsers are there
    We first took a look at Maxthon in 2008, where we noted that Maxthon began as an extension of Internet Explorer and so, it uses the same rendering engine. These days, Maxthon supports both the Trident rendering engine (which is the layout engine for IE, so you can still view IE-optimized websites) as well as Webkit, which powers Google Chrome and Safari and renders Maxthon’s Ultra Mode, loading pages almost instantly.
    In addition to its dual display engines, Maxthon also has a sea of nice features, such as mouse gestures, bookmark sync with Maxthon Passport, speed dial, popup blocker, online notepad, RSS reader, instant translator, screen capturing tools, and resource sniffer, which detects all video, image, and audio links on a website. The Android app also has a few of these features, namely the RSS reader, speed dial, download manager and gestures.

    Opera 11 [Cross-Platform]

    what new web browsers are there
    In addition to extensions, Opera contains a few more impressive features that make it stand out from the crowd. With Opera, you don’t need another desktop mail program, torrent client, or web server, as Opera offers these services. Since Opera also offers browsers for mobile phones and tablets, you can use Opera Link to sync your bookmarks, speed dial, custom searches, etc. Opera users also get a free space on the My Opera community, that they can use as a blog or to share files.
    One additional cool feature that we should mention is Tab Stack, which is one among many other tab management features Opera has, and can help you not only group tabs, but also streamline your workflow.

    Internet Explorer 9 [Windows 7/Vista]

    new web browsers
    IE9 is heaps better than its predecessors, and sports a more minimalistic look, but perhaps the biggest feature it has over other browsers is, without a doubt, its integration with the Windows OS. Jumplists definitely take advantage of sites like Twitter and Facebook, which behave more like applications, and make some functions more seamless.
