Just now it kicked in while I'm watching TV. I pass by my TV on the way in and out of the room so I always turn the TV on and off by pressing the button on the TV. So I assume the DVR does not know that I turned it on (or off). This is why I would like the option to disable the screen saver. It's not 1984, 1994 or 2004, I don''t have a CRT TV!
