There’s none, really. DivX is basically a step farther from the original hack of the MS MPEG4 v3 codec, which, after the beta phase did not allow to encode to AVI anymore so that limit was hacked out. Gej then changed the name and the fourcc code in order to allow both codecs to coexist. What is the difference between DivX, ASF, MPEG4, SMR, etc All these codes are based on the Microsoft MPEG4 v3 codec. ASF is Microsoft’s streaming format, but it uses the same codec. The official MS MPEG4 v3 codec only allows for ASF output, or also for WMV output using the Windows Media Encoder v7. There’s hacked MPEG4 codecs which remove the ASF encoding only limit, and the only difference between them and DivX/SMR/etc is that these codecs have another name and another fourff code identifying them. The tell the media player which codec to use during playback. There’s NO quality difference between the various codecs.
