Fix for iMovie + protected AAC music issues

If you're having trouble using a song purchased from the iTMS in your iMovie projects, Apple's posted an article covering a few steps you can take to get back on track. The first step, naturally, is to make sure that you're running the latest versions of iTunes, iMovie and QuickTime. Other steps include disabling any 3rd party plugins you might have installed for QuickTime and/or iMovie, as well as one trick I've never seen before: recreating the iTunes Music Library.xml file.

While this should be a helpful troubleshooting article, who wants to place bets on when we'll see tutorials from Apple on how to use iTMS video files in iMovie projects?
