I downloaded some avi files and burned them to a cd with toast set to create files for pc or mac. Anyway I gave them to a friend who has a pc and I thought they'd be fine because I was under the impression that avi was a pc thing. Anyway he could see the files on the CD but when he tried to play them with the WMP it brought up the error message "Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file". I checked on the microsoft web page and they say that WMP does support avi. Does anyone have any suggestions as to why these files are not playing. The files originally came from video.google EDIT: I just tried them on my WMP for mac and they also wouldn't play although they will play in quicktime and vlc.
