If it's exactly the same, your PC has RCA video/audio inputs on the back as part of the TV tuner card. Mine also has RCA and Svideo, inputs on the front, but they are connected internally to that same TV tuner card. It also has firewire, which I use with my video camera.

You need some recording application that can access those inputs. Window's Movie Maker 2 is free, and can probably do the job. Once you've captured the video, you need it in a format that your DVD burning software can use. It's up to you to figure that out.

If you have all the hookups, but the image looks corrupted, you may be encountering Macrovision copy protection. To get past that you'll need a SIMA video stabilizer or something similar.

Good luck.
