Winamp and Windows Media Player cannot play the unmodified .avi file because the non-standard file header corrupts the file. However, Media Player Classic, MPlayer, the VLC Media Player and GOM Player will play the unmodified .avi file, and the Google .mp4 file. Media Player Classic can do so only if an MPEG-4 DirectShow Filter, such as ffdshow, is installed. Most Linux media players (including xine, Totem, the Linux version of VLC Media Player, and Kaffeine) have no problem playing Google's .avi format.
