I just moved and the house I'm renting now already has a dish on the roof. The one at our old house only had one cable connection on the LNB and used the SWM. The house we moved to seems to have a different setup. There are four lines coming from the LNB into a Zinwell WB68 and then various lines to different rooms in the house. My SD receiver picked up a signal and gets all my subscribed channels without any error -- signal strengths in the mid 90's on almost every transponder. When I connect my HR22-100 to the same line the SD receiver was connected to I get no signal whatsoever. I grabbed a MSPLIT4R1-03 that was connected to the old dish and the one wire LNB from the old dish, but I have NO idea how to make this HD receiver work and I don't want to fry anything -- oh, I also have a power inserter from the old house, not yet connected to anything at the new house. Help?
