	You can download the full specs for Apple's QuickTime (.mov) files on 
their site. However, MPEG's extensions (.mp4), while *ahem* "open" are 
only open to those who pay to subscribe to their club. We implement .mp4 
with a minimalist understanding of those extensions.

obviously trying to make some QT/MP4 files. What playback mechanism are 
you aiming to support?
