Sorry for delay in updating. Found our problem was more than likely the addition of splitter in the "satellite in" coax. As the access to this coax was very tight and required a much more agile person to explore cabling, we drilled a hole in media area and ran coax direct from Tailgater to Receiver and will just pull the cabling inside when traveling. All is well and, during this process, we even determined how to connect DVD player via tv and receiver.... Thanks for all your help.
