This will allow you to play divx and xvid movies on MacOS 8.6 and later, it has been taken out of its homepage, now you can only find the OS X version.
3ivx is actually really useful because it creates standard MPEG-4 output. That is, at least ver. d4_451 does which is what I have. I'm not sure about this version--you'll have to try it.
What this means is that you can *export* using 3ivx, which is faster and better quality (per kilobyte) than QuickTime 6's built-in MPG4 codec, then playback using QT. Playing back *using 3ivx* leads to crashes (again, that's with d4_451). Of course, this may mean restarting with 3ivx removed from the extensions folder for playback, which isn't a big deal if you've exported a 60 min video....

The original upload is sitx-compressed. I've added a new link with 3ivx D4 4.5.1 taken from the original download page at archive.org.
