The beta expires in October. An interesting in the FAQ's says that, '... because QuickTime 6 will include royalty-bearing technologies, a new QuickTime Pro key will be required to unlock pro functionality in the final release.'" It is available for Mac OS, Mac OS X, and Windows, and supports AAC audio too. I also wonder why MPEG-4 is ".mp4". ".mp3" isn't for MPEG-3, after all. Flummery!
