Taping a TV???

I used an camcorder to tape a cutscene in a video game which was playing on a standard TV (NOT LCD or Plasma) but the screen would have lines running through and dark bottom/tops which where not there on the original screen. I am trying to tape it for my laptop, is there any wy to filter that out, or better yet, stop it before it happens?
