I am unaware of any MPEG hardware boards for the Sun.  We have the Parallax
XVIDEO board with a C^3 CL550 chip (JPEG) that we've been working with
for over a year.  The board is expensive (approx. $7.5K), but it works ok.
There is another board form another vendor that appears to be about the
same in performance and cost.

I'm the leader of the group that wrote the Berkeley MPEG software.  I'm
anxious to try it on the CL550 using the chip to decode the I-frames,
and doing the other frames in software.  My sense is that this should 
work very well.

We don't yet have public domain MPEG encoder software.  There are some
commercial software packages coming (e.g., from North Valley Research
contact toddb@nvr.com and mertan@netcom.com), and you can buy both
mpeg sequences and coder/decoder from C^3 but it is hard to get them
to talk to you.  I have also been told that several other systems exists 
but they have not been distributed yet.

So, the bottom line is that some pieces are available, they are expensive
if commercial, and more are coming.
