Why AVI files do not play on Mac?
Although QuickTime has officially added support for AVI files, however, there are still many people complain that QuickTime on Mac does not work with AVI files. As a matter of fact, most of those issues arise with movies that have been compressed using CODECs (Compressor - Decompressor) that are unavailable for QuickTime in Mac OS X. In particular, the Indeo® CODEC, popular for video compression on PCs, has not been ported to Mac OS X. The same issue also happens on many Divx-encoded files carrying the .avi extension. QuickTime does not include native DivX support, even though QuickTime 6 and later support the ISO Standard MPEG-4 media compression format and DivX is based on the MPEG-4 standard.
