go to capture video,, but im not sure if a camera hooked up through usb will be detected or cabable of this. if i understand what you originally asked , i think a tv card with composite video in would work. you would plug the cam into the vid in, and start using the cam regularly, then to record to your harddrive, you would press the record button on the viewing software you tv card came with. you would also be able to record live tv, playback video from devices onto your monitor, and if u wanted, record them.
