I downloaded some .avi's from kazaa. When I go to play them in either Window's Media Player or Real Player the player starts to download a codec for MPEG4. After it finishes downloading an error comes up saying the file cannot be played correctly. When I try to play the .avi the sound works, but not the video. Can someone tell me what to do so that I can view the .avi's? Also how can I burn these into vcds? I have tpmgenc.
