I wonder if this is what I've been seeing. I have a 722 with the OTA tuner. One day after watching the local news with the OTA tuner I found the unit was stuck there. None of the buttons on the remote seemed to have an effect other then pause and play. I power cycled but that didn't fix it. Hitting the reset button woke it back up. It happened again a week or so later in much the same way, only this time even the pause and play buttons didn't work. It took a couple of resets to wake it back up. Since then I've had a few other odd hiccups like it recorded shows I don't ever watch in place of those I had scheduled, and recordings crapped out in the middle, though the DVR showed them to be 1 hour long. For the past couple of weeks it seems to be behaving again. I was afraid the receiver might be about to die, but now I'm hoping it's just some software glitch that a new update will fix.
