Greg has a DVD/VCR combo, but it only plays in black and white. Leo says that the likely culprit is a bad composite cable (red, white, yellow). So he should replace that. They're pretty cheap. ScooterX in the chatroom says that in the memo of the DVD player, there's a setting that could be affecting it. The TV may be using the same jacks for component as it does for composite. He should check his menu settings. TomsGuide has information on how to do that.
