I've seen that mentioned several times now. Is that something in the new boxes? My 508 updates the guide silently, behind the scenes. It never interrupts viewing the way some of you have mentioned and I leave it on all the time. The only time I've ever seen it is when I turn the box on after an extended power outage. I do have the inactivity timer set for about 1AM, but I'm usually awake to override that several nights a week.
