I'm trying to watch an avi file that's has "xvid" in the title. The video works fine, but there's no sound. I've downloaded DivX 5.2 and stuck some xvid thingamajob in my quicktime library...anyone know how to fix this bloomin' thing?

Use VLC.

Because Quicktime doesn't support divx (avi) on its own.

Actually, the situation's a little more complex than that. QuickTime supports DivX video, DivX audio, and the AVI format individually. However, it's not supposed to be technologically possible to squeeze DivX's audio and video formats into an AVI file. This is an inherent flaw in DivX's original programs, which only ever worked because of a bug in Windows Media Player such that this combination just happened to work, but the result is that DivX "AVI" files aren't really AVI files at all. They're a broken hack of a bad file format.

The best way around this is to use a real container format, like .mov or .mp4 or even Matroska, since the AVI container format is complete crap anyway, but unfortunately these solutions aren't terribly common nowadays. VLC supports the broken pseudo-AVI format which DivX uses, so that's probably your best bet.

Ok, but see, I added the components that were supposed to make Quicktime work...any guesses as to why they didn't?

The only way to get an xvid avi to play in QT with sound is to (1) install the divx codec from divx.com, (2) install the xvid delegate from insaneness.com, and (3) not screw it up in any number of ways (like having conflicting or OS 9 codecs installed for OS X, or having not installed one of those things properly, or having a slightly corrupt (or incomplete) video file that VLC happens to work around without throwing errors). Any one of those steps might be the reason for your problem.

You say the audio is what's not working, right?

Do you know what kind of audio the file I supposed to have? Stereo, surround, etc.? If it's in AC3 format, then you'll also need a QuickTime plugin for that (or just continue to use VLC!).

If you don't know, VLC can tell you the audio properties of the file (command i, or "Get Info" from the Window menu. QuickTime Player can do this too but I don't think it can tell you if it's something it doesn't recognize anyway—duh).
