I just upgraded from an Onkyo 7.2/1080p system to a Denon system that is 9.2/4k capable. Should have been a _really_ nice bump in performance.... except.... We have an Amazon FireTV Cube and a DirectTV receiver. That's all we really use. Even the old Onkyo you could pick up the Amazon remote, hit a buttton and the receiver lights up, the TV goes on and away you go. Power off the TV, the receiver goes off, wife is happy. Pick up the DirectTV remote, hit the power button, the DirectTV receiver powers up, the receiver powers, the TV powers up, wife is happy. Power off on the DirectTV, and same thing. Wife is happy. Plug in the Denon -- Add two new height speakers and the sound is good, but christ almighty.... it takes 20 minutes of fiddling with the remotes and sometimes with the DirectTV we just give up and listen to audio from the TV because the receiver just WILL NOT STAY ON. I have called Denon support line and they have been ... let's just say less than helpful. That is probably the nices thing I can say about my experience so far. I have run through the setup wizards, and fiddled with power and HDMI settings manually, and none of it seems to work. I'm a day or two away from just boxing it up and sending ti back. I would have already if it weren't for the impressive audio and finally getting to see my 4k TV at 4K. Are there any suggestions or routes to take to get to Denon support that doesn't just make fun of you?
