The power in my house went out for a second yesterday, causing my HR54 to reboot. After the reboot, the HDMI output was showing as disconnected. The DVR was working otherwise and I could play programs from its playlist on my other DVR using the whole-home feature. After doing the usual troubleshooting, I placed a service call with DirecTV to get the HR54 replaced. A little later I decided to go into the hardware utilities by pressing SELECT as the HR54 was starting up. I didn't see anything other than hard disk diagnostics, so I chose the reboot option from the menu. After the reboot, the HDMI port was working again and everything was back to normal. I had this same issue a few months ago and had to have the previous HR54 replaced. I found some messages on AT&T forums indicating a lot of other people have had this same issue with the HR54, some of them repeatedly. Anyone have any insight on this? I wonder if I should consider switching to the HS17 and mini clients. I would probably get locked into a 2-year commitment, but since DirecTV has the NFLST package locked up for the next 2 years it isn't likely I'll be switching before then anyway.
