    I've got a video in "avi" format, which plays fine in the Divx player, but in Quicktime it plays with no sound. I've tried downloading and installing Perian, but it still didn't work.

    Files that end in ".avi" rarely adhere to any sort fo standard. Rather they are the bastard children of Microsoft's "divx" format that they proposed that the MPEG group adopt as MPEG4 (rather than Apple's format proposal that they accepted). Durring that development period everyone and their brother came out with mutually-incompatible codecs that were roughly based on that in-development format.

    VLC and others began life as collections of these codecs bound up with a player. They have evolved since then, but still cary their roots with them.

    Perian is also one of these, but it seems that it does not quite contain the version you need, or it is constrained by the QuickTime format (which has more rules meant to sync the audio and video), and can't play the particular form of audio that one has.

    What are the formats of the audio and video tracks?
