Since video playback was put into iTunes, it was limited to just Quicktime files. While this was fine, it meant that for those of us who wanted to manage our DivX files (which you can play in QuickTime with the DivX codec), we were out of luck. However, thanks to something I discovered in QuickTime Pro, you can now import QT-playable DivX files into iTunes. Here's how to do it.
1) Open your DivX file in QuickTime. You'll know if you have a valid movie or not because, well, it will be playable in QuickTime. 2) Choose Save As from the File menu. 3) Choose "Save as a reference movie". What this does is basically creates a file that wraps information about the DivX file (where it is, for example) into a QuickTime movie, but doesn't actually include the movie file itself. 4) Drag into iTunes. Bingo!
