I just moved from an area where I had my own dish to one serviced by an MDU. I have 4 HD DVRs and I HD Receiver, so I had a SWM16 connected to my dish. At the new location, I was told this would be fine. However, when the installer came out, he stated that they could only run 8 tuners from the SWM they had installed. There were 4 of these SWM units, one for each of four townhomes. I called back and they will be sending another tech out. So I am better prepared for the next tech - is it possible to cascade my SWM16 from their SWM so that I can get all of my receivers active and keep my whole home access among all of them?
