Hello folks. I'm new here and a new directive customer. I'm a little confused about the WHDVR connections. I've read about the cinema connection kit. I don't have the connection kit, I have a deca adapter which connects my router with the HR34 via ethernet/splitter/coax. Is there an internet signal which travels along the coax which is split to the HR24 downstairs? If I added another receiver would I need the connection kit? How are the HR34 and HR24 actually connected? Thanks for any information!
