AVI, an acronym for Audio Video Interleave, is a multimedia container format. An AVI file can carry audio/visual data inside in almost any compression scheme, including: MPEG-4, XviD, DivX and others.
AVI files can contain both audio and video data in a file container that allows synchronous audio-with-video playback.
You might have a bunch of VOB files, either from ripped commercial DVDs or homemade DVD videos. If you would like to convert them to AVI format for convenient playback on portable players, such as PSP, Xbox 360, or video editing tools, then this guide will show you how to do that with VOB to AVI DVD Ripper for Mac.
