Channel timing out?
My wife likes to leave the TV on for the dog when no one is home. Coming home several hours later, we find that the screen now says "Channel not available...". If I change the channel, then immediately go back to that channel, it is in fact available. So what's going on? Is it timing out or something while we are away from home? And if so, that doesn't help people that leave their TV on while away form home for security purposes.
