I've noticed this with my satellite receiver too. Powered up or down, the thing runs super hot. I've resorted to flipping the switch on my extension cord.
Satellite receivers (at least the models I have, plus the ones I've read about testing) use about 38 watts on and 35 watts in standby ("power saving" mode). Yes, you read that right. It manages to save 3 whole watts by going into power saving mode, which is now automatic with the new firmware (after four hours).
