My house is wired with cat 5 from my office to my bedroom and living room. I only have one TV, which is in my living room. Yesterday I had a HR34 installed, upgrading from an HR20, and the installer also installed a SWM and a DECA. If I am only using one television and and I have a direct Ethernet connection that can be plugged into the HR 34 is there any advantage to leaving it hooked up to the DECA? I can't think of any. My HR20 was hooked up directly to my network without any problems. Any help would be appreciated.
