I've had Dish DVRs since they first came out, but I've never had one last more than 3 years. I'd thought maybe I finally had a winner with my current VIP722, but in the last few days it's showing signs of dying. Locks up during playback, and then loses all DVR functionality until after a reboot. I'm guessing a matter of days now before it dies for good. To me this is pretty frustrating. I wouldn't complain if it were a new technology, but DVR has been out for a long time now, and I'd expect reliability should now be high enough to last more than 3 years. I'm wondering if it has something to do with the fact that every time I get a replacement unit from Dish, it's always a "refurbished" unit. I miss the days when I could buy my own DVR from Dish... So I'm wondering if I've just been unlucky, or whether this is a fairly common problem?
