I have an ND cube system.  I would like to be able to do multiple
successive frame grabs from my VCR and/or camcorder, at a rate of at
least 3 or 4 frames a second (a far cry from the promised 
real-time-video-to-disk rates).  It takes almost a second to complete a
frame grab, however.
 
I have been told that the frame-grabbing bottleneck is the speed at
which data is moved across the backplain to the '040 board.  Seems to me
that if that is the case, you could move 10-20 times more frames per
second if the ND board supported compression.
 
Anyway, this is one more reason for wanting compression on the ND
board.
