Satellite will not work if you are splitting the signal anywhere between the dish and the receiver. We have a DirecTV roof mounted dish, and we use a HD DVR. We split the signal between the two TV's on the "output" of the DVR and that will work fine if you are trying to connect multiple television's. Not sure what the tech was telling Bird Dawg, we've been using DirecTV in our trailer for the last five years and we've never once had an issue with our receivers. I will say that when we connect the signal from an external source, and use the cable input port on the outside of the TT, I unscrewed the "12-volt outlet/cable port" all in one unit from the wall and by passed the splitter they have inside the "12-volt outlet/cable port" combo. Let me know if that last sentence makes sense or not and I'm happy to go take a quick pic of it and post it for you if it may help you out.
