One possibility: It could be a DivX encoded file. There is a version of DivX available for the Mac and the one I downloaded has a little program to fix the audio on some files. I forgot what version number it is (at work, DivX at home) but I'm sure if you did a search on Google with the words "divx" and "macintosh", something would turn up. Or...It could be some other codec. Original message: ------------------------------ Date: Tue, 29 Jul 2003 17:55:07 -0400 Subject: [MacDV] AVI Conversion? From: Sean W.Gallagher Message-Id: <5105ECB5-C20F-11D7-892A-000393D39930 at greatertalent.com> I've got this AVI that QuickTime will not open. It gives that standard AVI message that it has a "compressor that quicktime does not understand". Does anyone know of a program that will convert it? I tried cleaner but it came out blank. I'm also trying to show up the PC user that created it who told me that the reason I can't open the file is that "Macs suck". -Sean
