Hello, I recently added a HD DVR to my equipment. The tech installed the HD DVR in room B. It was supposed to go into room A. I wanted to Take the SD Receiver from room A and put it in room B, and install the HD DVR in room A. I have run all the coax cable and was receiving video on both receivers before I moved them. After moving them, I received the error "searching for sattelite signal" on both receivers. I switched them back to their original positions, SD in room A, HD in room B, and the receivers worked ok again. Im not sure what I'm missing here. I thought for sure the receivers would work no matter where I moved them. Is there a step I am missing somewhere to get the receivers to work in their new locations? I have a good idea about what Im doing because I have 13-14 receivers in my house, however I never tried to switch locations of any of them once they were setup. Im drawing a blank here, so i think there must be something I have overlooked. Thank you in advance for your input. Have a nice day!
