Troubleshooting Video

Symptom	Possible solution
Some video files do not play.	Your file may be corrupt or in an unsupported format. Open the video file in a video editor, and then resave the file in a supported format.
Codec error messages appear when I play certain video files.	Open the file in Windows Media Player. Ensure Windows Media Player is configured to automatically download codecs. If the correct codec is available, the file will play. Note that you must be connected to the Internet to download the codec file. If the correct codec is not available, check to see if there is an update available for Windows Media Player. For more information, open Windows Media Player Help, and then search the online Help for codec.
