So today one of my recordings would not play, I would select start over and nothing would happen, I tried delete and nothing. I had to reset the box to get it to work. Then another one same thing. Now I try to play a recording from a couple hours ago and it says a problem was encountered when opening the files for this dvr event please note the error code:04. Very Frustrated. Any help is appreciated, and as we all know by now talking to customer service may give me a heart attack.
