More questions about the Movie-JPEG format, please:

- Why was it decided to invent a format rather than use the existing 
Motion-JPEG standard (which I didn't know about until Bolot sent me 
these URLs):

http://bmrc.berkeley.edu/research/cmt/versions/4.0/doc/cmtmjpeg/MJPEG_ 
chunkfile.html
http://neptune.netcomp.monash.edu.au/cpe3013/MPEG/Reading/MJPEG/step1.htm

The Motion-JPEG format sounds like essentially the same thing as the 
movie-JPEG format, but I could be missing some of the subtleties.

- Why is the soundtrack audio format Sun mulaw rather than something 
more common like AIFF or WAV?

- It looks like it's possible to do multiple soundtracks (though the 
MPEG-to-Movie-JPEG example only create a single monophonic 
soundtrack).  How does that work?  Are they mixed during playback, or 
is there a way to choose between soundtracks during playback?

I'm eager to get the plugin/VM to try it, particular on BUILDING some movies!
