I don't understand why it is so hard to make an electronic device, that just does what it is supposed to. It seems like DVR's in general are the worst devices out there. Other devices have electronic components too, but they never fail that often. A PC for example runs similar with a dedicated software, but from my experience I had less trouble with my PC, than I had with my 622. Even though I built my PC from all kinds of different components myself. The only times I had trouble with it, was either a virus, or human error. I had some power supplies dying, but I think it was electric current fluctuations.
