I had a new HR44 installed. It is now connected whole home with an HR-23 and HR-22. All work fine except the screen on the HR44 says the following: "Problem communicating with dish. Press SELECT on More Info. (776). I select More Info & get: A satellite dish hardware upgrade is required. Please call Customer Service and choose 776. The installer put in a SWM8 rather than a SWM16. Is that the cause of the error message even though I am not using all the tuners at once?
