Video Capture cards

I want to add a video capture card to my system, and would prefer to get one that is Linux compatible (while I don't mind that much booting back to Windows to work, I'd rather do that as little as possible). I'm sure some of you have them and was hoping that you could recommend some. I'm not incredibly opposed to an integrated display card and capture card, so please recommend either if you have them. Ideally, it should have both composite and S-VHS input so that it can accommodate both my laserdisc and video camera for inputs. tia ---Michael
