Does it allow the recording of 2 shows while watching a third? I had the box on all morning and its been fine but just as I was reading this I went to Ion plus on 103w and like a minute later its frozen. I don't have access to 99w right now because I moved the dish but it always locks up there as well. this is 3840H 26681. I am going to try and mess with the SR but its aggravating.
