One of my HR20-700 DVRs that I've had for 10 months now started overheating a few days ago. The unit has been in my entertainment shelf for the entire time and has never done this before now. I can hear the fan working inside (not sure if there is one or two on the HR20 - but I hear something), but the unit is suddenly getting really hot, even though nothing has changed in the environment. The unit was installed into the shelf by D* last September and has 4 inches of open space above it, two inches on each side and 10 inches of open space behind it, so I think it is adequately ventilated - at least the tech thought so that installed it. The only thing that I can think of that has changed was the new firmware release a few days ago - and I can't see why a firmware release would cause overheating. I'd appreciate any ideas folks have.
