I've also noticed quite a few medium-end video cards from nVidia and ATI come with video dongles that attach to a connector on the video card, itself, and allows you to do video capture. Check if your current video card has that ability. Some motherboards also have that capability built-in.

If you bought yourself a Windows Media Center PC, you're certain to have that ability.
