I have a Samsung MU9000 TV. In the past the TV remote would control the FireTV device. Randomly the TV remote does not recognize the FireTV device. I have noticed that when I attempt to add the FireTV device as a "set top device" in the samsung TV universal remote settings, amazon Fire is not an option. I do have my FireTV device connected through a home theater device, but this was never an issue in the past. Any ideas?
