My DVR seems to be randomly recording shows on channels I don't even tune to. I first thought it was someone else pushing record on another box in the house but since only the DVR (7100-P2) can record shows that isn't the case. I am the only one that uses the DVR box and am not accidently pressing record;
You're right, the box is actually the 7232-P2, I mixed it up. The thing is I only record hi-def channels and don't even tune into SD, yet HBO SD and another SD channel just randomly recorded. I really don't know how this happened.
