I have a dual LNB dish that is connected to a Zinwell WB68. I have two DVR's connected that are using the first 4 outputs. The other 4 outputs run into 2 different rooms. I am trying to connect a standard receiver in one of those rooms and when I plug it in it just says that it is searching for satellite signal. The receiver has been activated. Does it have something to do with the coax cable? Since there are 2 that run into the room and I only need one for the standard receiver? Thanks.
