I have 3 Samsung 4080s. Two are in use, zippered, and expanded. One is not. One of the 4080s is pixelating pretty bad. Can I swap my zippered HD into the deactived unit and keep my zipper. I know that I'll lose my shows and stuff, but do I have to run all the telnet stuff again, or just guided setup. I don't want to get a new receiver now because I am about to upgrade one box to a HD DVR.
