Okay, I have an oval dish with three lnbs and four lines coming off the dish. Two went to the LR for the dual tuner dvr, one ran to the weight room to a standard receiver, and the fourth to the br to a standard receiver. I deactivated the weight room and replaced the br with another dual tuner dvr. Needing another line for the dual tuner dvr now in the BR I pulled the line going to the weight room and routed it to the BR , however it was not long enough and I had to get a coupler and tie into it. Got it all hooked up and it will not receive signal through the line that went to the weight room. I figured four lines coming off the dish, two to the LR and two to the BR. Is this the way it should be done. Its driving me crazy, any input would greatly appreciated. Thanks.
