It's an dead format, move on. No I'm just kidding.
It should hace the RCA cables in the back to hook it up, so you could plug a "Y" adapter for RCA to mini jack and plug the mini jack into the line-in port on your sound card and capture the audio to the hard drive. Then you can bun the audio to the disc.
The only thing I don't know about is how to get the text for the karaoke on teh track, but I'm sure there's some software that will be able to do that.
