Sometime in the last month, my Hopper started asking if I was still watching a program if I hadn’t touched the controller in a while, and it shuts off the program if I don’t respond. This is annoying, but I can deal with it if I am home. However, I like to leave the TV on for the dogs to watch when I leave home for a few hours, and they have no way to respond. Is there any way to eliminate this “feature?”
