Well, I don't know anything about capture cards, but I do know that I will need one to hook up my Playstation 2 and Dreamcast to play them on my computer monitor. I have a few questions. What is the cheapest card possible for this? What ports does the card need? What kind of quality will it be, is it worth it? Can the video input be played on one of my two monitors or will it have to be both? I am purchasing a card to eliminate the hassle of a TV and VCR at college. Will I need any software to see this input concurrently?
You don't need a video capture card, you need something like an ATI All-In-Wonder or similar TV card. You'll have composite and CableCoaxial inputs. Everything you'll need software-wise will come with it.
