[geeks] video capture?

[der Mouse]

I want to set up video capture capability.  (Why?  I've taken it into
my head to try to build a system to automatically play a console game
(PS2, to be specific) and this requires some way to capture the video
output for the software to pick apart.  Not because I can't play it
manually, but just because it seems like a fun hack.)

I've gone through my stash of cards, and I find only one that appears
to be capture-capable, and it's an nvidia (meaning, no documentation,
as far as I can tell - there's an ubuntu driver, but it appears to be
one of those "big binary blob" drivers and thus useless to me - I don't
run software I didn't myself build from source).

Naturally, I'd prefer this be on a Sun, but I suspect it will be hard
enough to find the hardware for that that I'll have to settle for one
of my peecees.  The video can be either the TV-ready signal or the
output of a scan doubler I have which feeds into a peecee monitor.  (I
don't have a TV; the scan doubler is how I play console games.)

Any suggestions?  Or have I set myself up with requirements that in
practice amount to contradictory?
