Audio Will Play But Video Won't (Or Vice Versa)
Make sure that your computer has a sound card to play the audio. If you do have a sound card, the content that is being played probably uses a compression codec that is not installed on your computer. To make sure that you have all of the codec's that are currently supported, reinstall or upgrade Windows Media Player.
To do so, visit the following Microsoft Web site: Microsoft Download Centre . http://www.microsoft.com/windows/windowsmedia/download/AllDownloads.aspx?displang=en&qstechnology=
Windows Media Player 9+
1. Open Windows Media Player and right click on the menu bar and select Tools (If you have WMP 10/11 you may need to click the arrow in the top right hand corner to see this option)
2. Then select options
3. In the Player tab ensure Download Codec's Automatically is checked
4. In the Privacy tab ensure Acquire Licenses Automatically or Download Usage Rights Automatically when I play or sync file is checked
5. Select the Help tab
6. Choose Check for player updates
7. Ensure Download Codec's Automatically is checked
If you are still having problems after trying this please click on the following link and download the codec package http://www.microsoft.com/downloads/details.aspx?FamilyID=06fcaab7-dcc9-466b-b0c4-04db144bb601&displaylang=en
These settings should ensure your media player is always up to date and will update itself if any new codec's are to be downloaded.
This issue may also occur if there is not enough bandwidth to play both audio and video. You may receive sound even though the video is not present because audio requires less available bandwidth.
You can also try the following:
Video Acceleration
Please follow the instructions below
Click Start
Select Control Panel
Select Display
Then Settings - Advanced
Troubleshoot
Video Acceleration slider - move this to none and then apply.
Go back to the page you were viewing and press ctrl + F5.
This process is completely reversible and we recommend that you save this email for future reference as it can affect the playback of other devices such as DVD.
