How can I turn my monitor into a TV using my computer as a relay? - turn monitor into tv

I love my GeForce 7600GT and 1 S-video and 2 monitor connections on the back. Can I operate my computer as a link so you can not connect (eg DVD player or video camera or other) in the S-video and broadcast in my monitors, which are being monitored, such as the independent television to act?
