I have an older HR20-700 that may be dying, and I need some advice. *** Note that I mistyped the model number on the thread title. I have an "original" HR20-700 *** Symptoms: 1. I have 3 D* DVRs, WWDVR. This is the only unit with an issue. 2. Watching recorded material from the other DVRs works fine. 3. When I watch live TV on this DVR, the picture pixelates and I occasionally lose audio. This pixelization is like the old "Green Slime" we all saw a few years ago, but there's no green per se - rather, it's big and blotchy. 4. Signal strength is fine. 5. I once reset the entire unit, and it worked fine for a while. I'm planning to run a "Level 2" test today. I'm thinking the drive is dying. If so, would you just add an ESATA drive? If not, what are you thinking? Thanks so much!
