VLC Media Player, free for download at Videolan.org, is a powerful video player and transcoder (converter), capable of capturing and exporting streaming video, as well as converting to and from a number of audio and video formats. There are several ways to troubleshoot your VLC Player, depending on the problem. It may be a simple problem--as easy as quitting and restarting VLC--or a more advanced problem involving your video card. Other common playback problems with VLC may be due to your Preference settings or from trying to play a codec that is not currently installed in your player. If you have a problem you cannot fix by using any of the means here or at VideoLan.org, you can report it to VideoLan.
Fixing VLC 'Bugs'

Video of the Day
Try deleting VLC's configuration file, which is located in your user directory.
For Windows XP users, VLC can be found in your C-Drive: C:\Documents and Settings%username%\Application Data\vlc\vlcrc
For Mac OSX Users: HOME/Library/Preferences/VLC
Download and re-launch VLC.
Upgrade your video card from its manufacturer; for many, this is a free upgrade. Or, try disabling your video's overlay by clicking "Preferences/General/Video" and de-selecting "Overlay Video Output."
Change your video "output module" by clicking "Preferences" and selecting "Video." Click "Output Modules" and try choosing a different option (VideoLan suggests trying the "DirectX video output," which claims to have helped many people who experience "purple video").
According to VideoLan, VLC does not support "WMV3, the most recent Real Player and the most recent Indeo Video ("IV50")" files.
