My roommate bought a Toshiba HD-A3 HD-DVD player yesterday. We were removing my old DVD player from my entertainment center and putting in the new player. That was when I realized how hot my HR20-700 was. I was quite surprised. Here is a somewhat old pic of my setup: On the left side of the rack, starting from the bottom, you can see the Xbox, my old DVD player, and then my receiver. When I got my HR20-700 about 4 months ago, I just adjusted the receiver shelf up a bit and put the DVR on top of my old DVD player. There wasn't much room for clearance/ventilation on the top or bottom, but a decent amount on the sides and the back. I have had no problems with the unit flaking out or anything like that. Luckily, the new HD-DVD player has a slimmer profile and therefore the DVR now has about 2+ inches of air flow over the top of it. My questions are is this enough ventilation for the DVR? Also, since the DVR gets so hot, will it cause problems with the HD-DVD player? Thanks.
