As title says. Have US box from walmart. Denon Receiver. If I switch my input to my PS4, the receiver automatically switches back to the mi box. Tried different cable and input same problem. I use CEC a lot, turning it off is a major inconvenience. TV is Samsung if that matters, but when I turn ofd Anynet the problem still exists.
I have the same issue, only plus the screen flickers and distorts about every 5 seconds when hooked up to my denon 2200w.
