I currently have an HR22-100 and two HR20-100 HD DVRs with a SWM 8 setup. Looking to upgrade to a Genie for the living room. If I only replace an HR20 I figure I have to upgrade to a SWM 16 for 9 tuners and I could see why they'd want to bring in a professional. But if I get a Genie and one client to replace both HR20s I should be able to stick with the SWM 8. But no matter what configuration the tech put in it said that the Genie requires professional installation. I know my brother-in-law installed his own. It looks like several others around here installed their own. Why is their system blocking me?
