I wouldn't touch the ATI or NVIDIA ones with a 10ft barge-pole.
They're alright for watching TV, but not for recording resonably high-quality to scale down.
NVIDIA PureVideo is good, but you only get that with the lastest cards (6200/6600 only)
You will be able to directly throughput from your PS2 from it's RGB or RF on the Pinnacle. Most of them give you a little box that connects to the DVI. They've a little demanding on the processor though, so when recording the video you'll want to make sure that your not doing alot else.
Another thing is I'd recommend storing the video in RAW format then converting to an MPEG4 format later.
Dunno what the ATI one records, but I think it's max was 400x300. That said I've not used one of the lastest one, last one I had was for my 8500.. so it was a few years back. It was horrible though
don't think I ever used it past experimenting.
