What codecs do you need to have enabled in FFDShow so DVD's play in Windows Media Player? I'm getting audio but no video from my DVD. I must use Windows Media Player 11 specifically for this. I've installed the Vista Codec Package (on XP!) which comes with FFDShow and everything is default. I can play videos but not from DVDs. Only the audio comes. I've also tried CCCP. When I go to the video decoder configuration in FFDShow, MPEG-2 is disabled, and if I enable it as libavcodec, the DVD tick box under it says its not currently working. Graphics drivers are updated on the 7800 GT.
