This is as good a place as any to ask about Windows Media Player 11. Something happened recently to my player and I can't see video in MP4 podcasts. I get an error saying that a codec is needed (MPEG-4 Video (AVC1)). I have another pc with the same version and it works fine. What could cause the codec to suddenly disappear and how can I add it back? I tried uninstalling and reinstalling the media player.
