I have a Power Mac G4 400 AGP Graphics with 256 megs o' ram. I am in the market for a video capture card/external, whatever. I'm thinking I want to go with Firewire over USB because of the higher data rates. Does anyone have any opinions about what peripheral type to go with, and any specific brands that are good. I want something with good quality, but won't lighten my wallot too much. Thanks
