I have a denon avr sbt500bt receiver. Roku was working just fine until sometime last month. I think may be a Firmware update stopped it to work. I can plug in the roku in my monitor or projector and just works fine. It only doesn't recognize my AVR. Also, i noted it is extremely hot to even touch the roku when it is on.
I feel like other media players are better. And they all work right in all platforms.
