Couple of questions:
Do you get the NBC station as a LiL or off-air? Do you receive the NBC station in HD?
You could be getting totally different audio feeds for your HD and SD DVRs. That could account for the problem and it could be a local one with your station. I would tend to suspect that if it is only on a couple of programs. Problems with DirecTV's signal are usually more global.
