I'm in just about the same boat - can anyone confirm/deny that the Next wil
do full resolution, 30fps arbitrary video from the hard disk? A friend
tells me that the C-Cube JPEG chip simply doesn't work, at least not at
full speed/bandwidth video as they claimed.

I would also much prefer an add-in board.  I've seen a demo of a system
running on a Mac II playing "Star Wars" off the disk, 24 bits, 30fps,
using a jpeg system (but not the C-cube chip).  It was very glitchy.  I
think the company was Super Mac Technologies or something like that.
