I'm afraid this is just how DirecTV DVRs work. They simply don't respond in real time or consistently. Some suggest pressing OK first to get it to respond.

I don't recall the exact frequency, but DirecTV RF remotes are in the neighborhood of 400MHz, which doesn't overlap with routers or phones or microwaves at all. I have heard of things like wireless thermometers interfering, but that's rare. Unfortunately, I predict nothing you do will make any difference. The problem lies in the design of the DVR and it's software which has always had this problem to some degree and probably always will.
