Well, a Bt878 can capture from only one input at a time. In most cases this means you have to switch between inputs. If the inputs are all using the same sync signal, you can switch between them very quickly. Cards with multiple Bt8x8 chips exist, and there are probably cards that can combine four video streams into one. The point is, if the card isn't already supported, you have your work cut out for you. You can start by telling us what card it is, and what all the chips on it are. - Eric
