I've had this message a few times but since it just happened again I thought I'd ask why I'm getting it. Message is "Due to inactivity your receiver is about to shut down. To keep viewing press Continue or No". I turned the 722 on at 7am and received the message at 9:45am which means it was only on for 2hr and 45 minutes. I've had quite a few problems with this receiver lately and wonder if this is another bad indicator.
