Are you trying to capture video digitally or using analog?
If digital I would purchase the firewire card. If analog, I would purchase the Matrox G400 with the Video capture support. Its probably better than the ATI Radeon 64 Meg DDR VIVO, but I went ahead and bought the ATI because of more features. It is suppose to capture higher than 600+ resolution @30 fps but I haven't been successful at capturing at that high of a resolution. It is still good quality in capturing videos.
