Try going to “http://www.divx.com/divx/download/index.php” and get the divx for mac os x. Also 39vx.com has a codec that works, but both “divx for mac” and “3ivx 4.5” codecs can not be used at the same time, just one or the other.
As you know AVI is a container format, not a specific type of file. When QuickTime opens an .AVI file, it checks to see which codecs were used to encode the audio and video tracks within it. For example, an .AVI file may contain a video track encoded in the Cinepak codec and an audio track encoded with the ALaw 2:1 codec. If both the audio and the video were compressed using a codec that QuickTime can use, the file will play normally. If the audio or video or both were created using codecs that QuickTime cannot use, you may see a message like the following:
“QuickTime is missing the software needed to perform this operation. Unfortunately, it is not available on the QuickTime server”
