Turn Off HDMI Control
If you are using a HDMI cable then there is a good chance that they have the HDMI control turned on. This is supposed to make things easier and "smart" but I found it a pain and disabled it through the set-up menu on my TV, BR player, and anything else that has it.
The only real thing us lose if you disable HDMI control is things turning themselves on and off automatically and it does not sound like that is a welcom feature to you, as it was not for me.
So check your set-up menu on your TV and look for something that says something along the lines of HDMI Control or words to that effect and it should have an option to turn it off.
