I currently have 2 HD DVRs and 2 HD receivers (sorry, I don't have the model numbers) connected to a Slimline dish with 4 cables running into the house. Each of the DVRs has 2 coax cables connected. Occasionally, we take the 2 receivers camping in our motorhome. We have a Winegard Trav'ler on the RV and I understand they don't play well with SWM receivers. What I would like to do is get a Genie to replace one DVR and keep the rest of the hardware the same. Can a SWM (Genie) and non-SWM receiver coexist on the same network?
