Hi all, I have a problem and a question, so let me provide you with some background info. I've been experiencing pixelization on some channels on multiple receivers. I had DirecTV come out, and they replaced the dish, some connections, and the grounding block. The pixelization seemed to disappear, except for one tuner on the HDVR2. The guy wanted to set me up with a new DirecTV DVR+, but I decided to hold off. I have one more test to do, but it really is looking like a bad tuner. If I go to ESPN2 on one tuner it looks fine, switch off the channel and put the other tuner on ESPN2, it's pixelated. The last test I want to try is switch the 2 cables coming in. We tried the cables hooked up to another receiver, and it seemed to be ok, but I want to do this last test to make sure. If the pixelization stays with the tuner, then I know it is a bad tuner. If it switches to the other tuner, then it is a bad cable (or connection). Ok, now that I have the background info out of the way, here's my question. If I buy off eBay (or wherever) a unit w/o a hard drive (or with a bad hard drive), can I just put my drive into this unit? What about the access card, do I use mine, do I need a new one, do I need the one for the purchased unit? Any other pitfalls I might encounter? I have upgraded my HDVR2 to 107 hours (120GB drive, still have the original drive on a shelf). I have a lot on there, and I don't want to lose it. But, I also don't want to have to get a new DVR+ and have to switch back to my HDVR2 when I want to watch something off of it. Any suggestions?
