I'm going to try the line length solution, on my HR10-250 and my sir60 I get great reception on 95% of my channels, with the exception of CBS. I get occasional pixelization on. On the HR20, I don't get CBS, ABC, WGN at all. NBC and fox are strong. When I plug the antenna line directly into my HD TV its tuner can pull all of them in with no problem. Hopefully a software fix will come soon. I got my HR20 at best buy, and only have the triple lnb dish. Directv is saying probably February before they can come out and install the 5 lnb dish. The Chicago installations are all screwed up. I asked DTV to send me a dish and I'll install it myself but they refused saying it is too fragile to ship. I'm tempted just to get one from ebay.
