   I'm starting to feel guilty sitting on the sidelines.  I guess I'll
jump into the game for this one.

   The biggest question with NTSC vs. PAL is where you intend to
distribute your product.  NTSC is the official standard in the U.S.
while PAL is the standard of choice in Europe and much of the rest of
the world.  Thus, if you intend to market in the U.S. of A. NTSC is the
most appropriate choice.  There have been some interesting discussions in
comp.graphics on the relative technical merits of the two formats.
  I have heard a rumor that there is a videodisc player on the market
which will play both formats.  Has anyone heard of such a beast?  (I
would LIKE to believe this is true.)  There are overlay cards, such as 
IBM's M-Motion, which will support both NTSC and PAL input.  This kind
of system helps to reduce system configuration restrictions a bit.
