If you have a video card or TV tuner/capture card with a video in, just plug the yellow RCA connector from the camera into that. I'm sure if you search for webcam software out there you can find something to run it for free. If you don't already have a tuner card you can probably find one for around $20-30, but for that much, if you don't care about the TV recording, you might as well just buy a dedicated webcam that will include all the software you need,
