To purchase a Roamio Plus and a couple of Mini's. Have questions in regards to hookup, local cable co., and your experiences. The Hookup: Will use the cable in house as the hard wire hookup between the Roamio and Minis. An internet connection is not available at each TV location. When reading Roamio reviews on amazon I noticed people frequently purchased a MoCA "POE" Filter when also connecting mini's. It seems as if the Mini's work better when a filter is connected. However, less clear was where and how to hookup the filter. Can you help? Charter Communications in upper MI: Has Charter provided the proper cablecard to work with Roamio? If so, can I pick it up or do they require an appointment for them to come and install it themselves? Your Experience: In your experiences of the hookup what else should I have, be prepared for, or do when hooking up TIVO? Thank you in advance for your help.
