My HR21-700 updated to the new software on Dec. 14. That evening when I turned on the TV for the first time I got the announcement for the new Cinema feature, which basically alerted me that a new software build was installed. But things went downhill pretty fast. That evening I observed numerous pauses of roughly 15-20 seconds during live and recorded broadcasts, something I hadn't ever seen on this receiver in the 2+ years I've had it. Then the next day when I turned on the TV it seemed fine, but the receiver was not responding to commands from the remote or from the buttons on the receiver. I waited several minutes and no change. Finally had to hit the red reset button. After it rebooted it was fine, but I still was getting the pauses during live and recorded shows. And then at one point the receiver just rebooted itself while I was watching a show and doing nothing with the remote. The next day, same behavior. Receiver was frozen and required a reboot. When it came up I noticed that a few shows that would have recorded during the time I wasn't using the TV were in the play list, but had zero minute recordings. I had to reboot at least two more times that night. Same thing today. Finally called DTV. The initial responder did a couple "tests" and passed me on to the next level support. They had me reboot, do a system diag by holding the info button for about 10 seconds. It gave me a code which I provided to the CSR, who then said it didn't sound like a hard drive problem but they would be sending me a new one. So, I'm curious, just coincidence with the software upgrade or definitely related? The CSR said this sounded highly unusual based on very few complaints since the updates went out on the 14th and 15th, and I didn't see anything in the sticky thread about any major problems like this. Was my DVR just due and this update just put it over the top? Also, the CSR couldn't (or wouldn't) tell me what model receiver they'd be sending me. What should I expect, and what should I be really fearful of (if anything)? Aside from this latest incident and the occasional annoying response lag between the remote and receiver that I just sort of got used to I've been mostly pleased with the performance of this particular model.
