  After the upgrade to 16.0.1 some just Youtube videos won't play. They work perfectly in Chrome.
  A few examples:
  http://www.YouTube.com/watch?v=rQpldNJXuP0
  http://www.YouTube.com/watch?v=-e-BRki7gwU
  Most of the videos works perfectly, so I can't say what the problem is.

  I have tried so that the first thing, but it didn't work at all.
  Anyway, I solved the problem in the meantime by uninstalling Firefox and put it back. Please note that I had to do a CLEAN install, and I mean by 'clean' that I had to remove the settings as well. First I tried to reinstall it but I kept the settings (Firefox will ask if you want to keep when you uninstall) and it did not work. I therefore saved bookmarks and uninstalled everything. The later resettlement has solved the problem.

  IPHONE 5 C WON'T PLAY VIDEOS

  Try resetting your device. This will not erase your data stored on that device.

  • Press and hold the sleep/wake button
  • Press and hold the Home button
  • Press and hold both buttons until the display turns off and on again with the Apple logo on the subject.

  Alternatively, you can go to settings - general - reset - Reset all settings

  If that doesn't work, restore your device to factory settings. Please note that this will delete the data on your device.

  Take a look this Apple Support article: use iTunes to restore the iPhone, iPad or iPod to factory settings - Apple Support.

  As a final step, try recovery mode. Turn off your unit, then plug it to your computer with the hold home button. Hold down Home button until you see the logo of iTunes on the screen of your device. After that on your computer, you should see the iTunes window saying that your device needs to be restored to factory settings. Click Restore.

• Why Divx won't play video with sound on Firefox, but will play with sound on Chrome?

  DivX will play movies based on the web in both sound and audio on Chrome.

  DivX will play only video on Firefox.

  I've deleted and reinstalled Divx on my computer.

  I have a desktop running Vista.

  I just became aware of this problem yesterday. In the past, I got no problem to launch these videos on Firefox with the sound and video.

  I had this problem with videos at home yesterday as well.

  I've also seen this conversation http://veehd.com/forum/viewtopic?f=523714 and it may be a codec problem? No one has confirmed yet.

• Windows Media Player won't play videos

  I have Windows XP Home Sp 3 with all updates.

  There are three computers in my house, all with the same OS.

  We'll play videos and memories on TV with Windows Media Player slideshows, but others will not.  Who will play has been longer and maybe have a better codec.  Otherwise, I don't know why.

  I prepare a thesis on slide TV show which will be sent to about 100 people.  It is the DVD-R format and will probably be played on DVD players for which there should be no compatibility issues.  Some will want to see on their computers, however, and this is where the problem arises.  I use mostly WinDVD, so I have no problem, but what do the people who have that WMP?

  I don't understand why WMP should do by default.  Do I say to people who want to see the DVD on his computer?

  Hello

  You have converted this file to windows media player supported file types or they should have DVD decoder installed on the computer.

• HP Pavilion dv7 won't play videos on you tube

  When I get e-mail or message to watch a video on you tube and clik on the link, the video says an error has occered, try again. At first view, it was the YouTube site, but it happens all the time.

  It is a purely software problem, has nothing to do with your computer laptop itself.

  first step should be updated or reinstall the plugin used to play videos in the browser, which is especially the flash drive. Install it from http://www.adobe.com/go/EN_US-H-GET-FLASH

  If this does not help, uninstall flash completely http://kb2.adobe.com/cps/141/tn_14157.html and then reinstall it from the link above.

  If it persists, your browser (or another plugin) has a problem. Take a look at this http://support.microsoft.com/kb/923737/en-us

• Windows Media Center won't play video, but Windows Media Player will be?

  I'm reading a video .avi with the xvid codec. I installed the codec earlier and it plays fine in Windows Media Player, but when I try to play in Windows Media Center, it indicates that one or more codecs are required to play this file, but they cannot be found. I know I would just watch with Windows Media Player instead of Media Center, but I want to watch it on my Media Center extension (my Xbox). I'm running Windows Vista Ultimate, 64-bit. Why does Windows Media Player with this codec and Windows Media Center not work? How can I solve this problem?

  -Slick05_1

  Hi Slick05_1,

  Thanks for the replies on the forum.

  Given that the Microsoft Vista Media Center and XBOX do not play the files suggest it would need to be a codec which solves the problem or maybe file conversion which would solve the problems you are experiencing.  Since the codecs for files is not something written by Microsoft, we do not have the information for that in our system.

  What I suggest is to go to your search engine preferred and in the search line and typing "is possible to play VLC on XBOX.

  WARNING:

  Using third-party software, including hardware drivers can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the use of third-party software can be solved. Software using third party is at your own risk.

  What I suggest also done an online search using your favorite search engine for "play MKV files in Vista x 64 Media Center" to find whether there may be suggestions about codecs or these codecs created by other organizations then Microsoft.

  Please let us know if you are able to get this to work for you.

  Best regards
