Just happened to us, too. My wife is flipping out. Kids said that they were having trouble recording for the last couple of days, and the DVR was saying that it was full. I hadn't viewed anything on the DVR in the last few days, so I couldn't confirm or deny that part. But last night, it froze, went blank, reset and came back. No big deal there, but now today my wife reports (and I confirmed on my Verizon FiOS app on my phone) that the DVR was wiped clean.
That is infuriating, and we'll be seeking a discount. We had lots of kid movies recorded that the kids watch over and over, and my wife has several series recording that she catches up on a few days later. I know we can access some of that stuff On Demand, but it is nowhere near convenient or fast, and On Demand doesn't track what we already watched.
Did I mention this is infuriating? FIX IT VERIZON!
