I always keep my receivers on(HR24-500,HR23-700,& HR22-100). I have native setting on. I notice lapses on HD channels when going from 1080i channels to 720p & vice versa. There are times though when the lag seems longer than usual. I also have occasionally had the picture become wavy on my HR24. Rebooting takes care of that. All of my receivers have the latest CE,but the lag seems to have been going on for weeks.
