First I'm new to any of this forum posting so let me know if in right place. Ok. I have a slimeline 5 dish that was apparently installed with no multiswitch, swm, nothing just direct line to one receiver. I recently installed a DVR myself. DirecTV said there should be splitter but there not, they would not help me said I needed a service call to install anything else. What do I need to split 2 lines to DVR for recording & watching something else. And I want to run old hd receiver to another TV. Please help. Do I need multiswitch, swm,power inserter, special coaxial, more b band converters??
