You can play almost any AVI under OS X with: VideoLan Client: http://www.videolan.org/ or MPlayer http://mplayerosx.sourceforge.net/ Or, with the proper codecs installed, QuickTime will play just about every type of AVI file. See: http://www.lordofthecows.com/avi_qt.php An Apple KnowledgeBase article entitled "QuickTime : About Playing .AVI Files" can be found at <http://docs.info.apple.com/article.html?artnum=93199> . The problem is that there are a number of different types of AVI files and you need to have the codec installed that works with the AVI that you want to open. You can tell what codec was used in a given file by opening the file in Quicktime and choosing 'show movie info' from the 'window' menu, and choosing 'properties.' There is another codec called DIV 3. You can open these AVI's with software called DivX which you can get from: http://www.divx.com/divx/mac/ DivX4Mac is a player that supports the high quality DivX video codec http://download.projectmayo.com/dnload/divx4mac/OpenDivXInstall.sit I hope this helps.
