I currently have 2 H-20 receivers hooked up to a Slimline dish. One of my receivers is having issues and not able to tune to a large chunk of channels and/or showing that I haven't purchased channels which I have. It's definitely the box as I've swapped the two and it behaves the same on the other line. I was going to replace the faulty one and was considering getting an HD DVR. (I currently use a HTPC for the main DVR). My question is around what lines I'd need to have from the dish to the receiver. Now I just have two lines from the dish, one to each receiver. There's no multiswitch. Would a third line need to be run to have two for the DVR? My concern is that I'm in Minnesota and there's a significant amount of snow on the roof at this point. I'm not sure they would even attempt to go up there. Can anything be done that doesn't require going to the dish? Also am I missing anything on diagnosing my faulty receiver? Should I not give up on it? It's been restarted/reset many times. It does the same thing on either line from the dish. Thanks for any help.
