I have been using the DirecTV iPhone app for some time with perfect results on my HR34. A couple days ago I came home and found that a recording that had been program successfully via the iPhone app had not recorded. The same thing happened with every program I have tried to record this way since. Tonight I rebooted the HR34 to see if that would make a difference but it did not. I can program a recording directly on the HR34 and it will record but not with the iPhone app even though I get a "successful" reply.
