I've had this crop up a few times since I've had the 622 (Feb.) While scrolling down in the DVR schedule menu I get about 2-3 days down and it freezes for a couple of seconds and then re-boots. I haven't had it happen in a couple of weeks but this morning it has done it twice. Anyone else run into this? I don't believe it is software version specific since it's happened on all versions I've had.
