How can I get composite or S video on to my laptop?

Basically, I have a video device that outputs either composite or S video. What I am wondering is how can I get the output of the video device on to my laptop? Is there a certain card I need to install?



Thanks|||I think edward's links might be the opposite of what you want. You want composite or s-video to go -to- your computer, not output from it, right? You'll need a capture device. Either a tv tuner or something like this:
