I helped my dad recently move. He had Comcast cable installed. The problem is we hooked up his DVD player, but I can't see a way to get the video mode. The DVD player is hooked up fine, I just can't get it into the video mode to watch DVDs. I know that the tv usually has that option on it, but I don't see it under the tv menu. I was wondering if there was a way to do this on the actual cable box. Thanks.
