You might be able to do it with a separate DVD recorder. Do you have an S-video output on your video card or your laptop? Plug it into the DVR input and use a patch cord from the computer's headphone plug to the DVR's audio input. (That would be a patch cord with a 1/8" mini-stereo male to two RCA male plugs). Hit record on the DVD recorder and hit play on the computer.
