I've got an old HR20/700 HD DVR that has served me faithfully for several years. I just bought a new TV (Panasonic ST series plasma) and have noticed that video coming from the DVR through my A/V receiver is showing a band across the top of the screen that is markedly lighter than the rest of the screen. This is particularly obvious in dark scenes. I am NOT getting this from my Blu-ray player, my media player or my Xbox, all of which go through the A/V receiver and into the same HDMI input on the TV. I am also NOT getting this from video streaming from the apps on the TV itself (NetFlix, Amazon streaming, etc.). Does this mean that my DVR is on the way out? From what I read on the service fees I'm paying monthly, I can demand and get a new DVR. Trouble is, the hours and hours of video recorded on the external 1.5 Tb drive I have would not transfer over. Or would it? Has DirecTV changed it's policy regarding "locking" video on external DVRs to the exact DVR they were recorded on? If I could get a new DVR and still watch what's on the drive, I would be a happy camper.
