I know electronics generate heat, and that's understandable while they are being used.
I was watching an HD program on my HD receiver (no DVR; just a receiver) and that program ended about 3 hours ago and I turned it off right after that program ended. The box is still unbelievably warm. Even in the morning, the box will still be producing heat. Why? DirecTV boxes don't generate anywhere close to that much heat (even when they are on) unless they are the DVR boxes, so why should this thing? I don't want to have to run my A/C more just because of the heat a box generates... pretty sad, and sad for the environment, too.
