If you're trying to record movies captured with your digital camcorder, can't you just connect your camcorder's S-video output to your VCR and record?
If you're trying to record movies on your PC, just connect your video card to the VCR and record.
If your VCR doesn't accept S-video, just composite (yellow connector), then buy an s-vid to composite adapter from Radio Shack or an online store. S-vid to composite connectors are included with most video cards, so NewEgg or Allstarshop should carry them.
