		Behind the scenes, eh?  ;-)

	Could you post references for this?  I wonder why they didn't tell
me this at COMDEX, since I specifically asked.  I also asked about frame rate,
which they said was up to 24 fps (from 15-18 a couple of years ago).  24 fps
is acceptable for full motion video (that's the rate at which film is played).
Can CD-I deliver at 30 fps, and at what resolution?
