I had a power outage this week which laster over an hour which was longer than my UPS's could handle so each of my boxes re-booted after the power came back on. After they came back up, the shows on the HR24-500 still showed in the list on the HR24-100, but when I tried to play one of them, it lost the connection and they dis-appeared from the list. I re-booted the HR24-500 and everything worked fine again, but I thought I should mention it anyway in case DTV wants to test those conditions. The average user probably wouldn't think about re-booting the box. By the way, all the boxes were on the NR and are connected over SWM and DECA.
