How do you record live tv programme of cable network or setup box to CD without tv tuner?

You must have a video capture card in your PC. A card that will take the signal from your TV settop box (video & audio) and record it on your hard disk. Once on your hard disk, then you can burn it to DVD or CD. You also need a capture software to do that. The software can either come with the capture card or you can buy/download a software from other companies like adobe , roxio, or Nero.
