A long time ago when I first got Mac OS X, I had a bunch of DiVX files and found a program that let me play them in QuickTime. Basically it took the video and audio out of the AVI wrapper and put them into a QuickTime wrapper. But now that you can play AVI's in QT w/ the help of codecs and VLC, is there anyway to return them to .avi? I'd like to share these videos with my PC friends but I'm not aware of DiVX codecs for QT on Windows.
