||The GVI format is similar to an .AVI file; it is encoded in DivX4 with an MP3 compressed audio track. They are similar to .avi files but have an extra list containing the FourCC goog immediately following the header. The list can be removed with a hex editor to avoid playback issues with various video players. The video is encoded in MPEG-4 ASP alongside an MP3 audio stream.
