Weekend before last, I moved my HR20 and HR21 around the entertainment center and now have them right around eye-level. The bright blue ring on the HR20 got a little annoying after a couple of days so I deceded to turn them both off. Much better. And I'll gain the added benefit of knowing when 0x034C showes up, though I don't care so much. A couple mornings later both blue rings are back on. Odd, I thought, since I usually get updates a day or two apart on the two boxes. Turned the rings back off but never actually checked the boxes. When that evening's TV vieweing began I checked the software version and was surprised to see 0x312 still on both DVRs. Hmmm... A couple of nights later, rinse and repeat. And then again, a night or two later. And again last night. I noticed it happened between 2:00 AM and 4:00 AM. So it's not happening every night I don't think, but every 2 or 3 nights, as best as I can tell. I didn't start paying very close attention until I noticed it happening several times. I don't understand why they would be resetting like this. They are both plugged into a UPS and the UPS is in good shape. If there was a power loss and the UPS was failing too, I'd get an alarm which I know is loud enough to wake me. Any ideas?
