This problem has been mentioned previously, but I haven't seen any good solutions. In my case I just started getting the overheated message yesterday. My unit is on top of a CD/DVD player that is off and is thus cool itself, which should provide a sufficient heatsink for the Roku unit, which itself is not hot but warm. If I let the Roku hang out in the air, I still get the message. No red light is on, so just what is the issue? Should the unit be replaced or what?
