Uhm, I don't think there is any way under the sun for a SS20 to move
about 200MB/s from disk to Memory to the video card.  I am even more
sure that compressed video won't work without a hardware accelerator.

Yes, except that 60Hz in computer terms means progressive in computer
terms, usually.  You need 60hz interlaced.  An HD scan converter can do
this if you can't figure out how to make the SS20 do it, but I think
that you might be able to configure interlaced out of some Sun cards.

Quite a few TVs support RGB actually.  For the rest, there are converter
boxes from Extron.
