Why does it sometimes only record 20 minutes of a 60 minute show?

There is miscommunication between the DVR and RG or your entire system and AT&T servers.  A reboot of the DVR should fix but you may need Tier 2 to do a rip and rebuild.

My whole system is on a battery back up/surge protector and even so there weren't any power failures. Hope it's not a sign of more glitches to come.

Can you tell if the power went off?  Battery back up or no, if the VRAD went down, I doubt any signal would make it and even then the battery backup only powers the RG and not the DVR.   Could just be a DVR "oddity" where the show stops recording.  AT&T Tier 2 would most likely like to know about this.

I had noticed that I had more and more oddities like that, DVR only recording partial episodes, black screens of death and so on.  I talked with AT&T labs and he compared the number of total recordings and number of scheduled series on my DVR and on his system and there were hige differences.  Apparently shows and scheduled series are not completely being deleted either on the DVR or on the AT&T servers.  This mismatch apparently was to blame.  The Tier 2 guy recommended a rip and rebuild where all series setups are deleted (and my DVR replaced too).  So far no partial recordings and one BSoD in over 500 recordings plated.  I exited out and went back into the list of recordings and the one BSoD played perfectly.  No rebooting required.  I'd check w/T2 to see what they are show is on your DVR vs. what you have.

  You know I never thought about the VRAD. It was extremely windy that day and the power here flickered. But none of my equipment rebooted because of my battery backups. Anytime the power flickers or goes out the first thing I always do is say "Oh s***" and look at my equipment and make sure it is still running. I guess it's possible there was a flicker at the VRAD that may have caused it. But don't they have the VRADs on an alternate power supply or backup? If the power went out at the VRAD it defintely didn't show up here in my equipment. Nor did it show an error using UVRT either. I'm just curious.
