I think it is called "Cantasia". Another option is a good camera with a clear screen shutter option. Output from a Raedon ATI card via S-Video is fairly clean etc.
I tried using my TV Out on my Radeon card right into my capture card, but the computer started to bog down (i had a p3-667 at the time). I'd recomend hooking your vid out to your camera/VCR, then playing that back and capturing it.
