I do have a desktop I could use I just figured a laptop would be more manageable and mobile. All I really want are mid grade quality 1 minute or so video captures though honestly I'm more interested in recording sound at the moment.

so i'm to understand the following setup won't work?

pentium DOS PC > PCI video card with VGA/composite/s-video out > one of those cheap $10 usb capture cards on ebay > laptop with windows xp?
