My bedroom unit is always resetting itself right in the middle of a show, never a commercial. No obstructions around it to slow heat flow, but very annoying. It is hot even when in the off mode.

Might just have to buy a new one for $99. Anyone have this issue?

Mine gets warm when on. But never hot.
Its rebooted about 5 times in the last year or so. Mostly during menu navgation..

H20-600 runs hot; H20-100 does not.

Maybe put it down as close to the floor as possible to keep it a little cooler. That's what I recently did with my Dish 322 tuner, which is always hot, on or off. I've had it for over 2 years, so apparently the heat hasn't affected it any.
