Coming back to Tivo after a few years with Directv (wife hates the Directv interface). I am looking to build a Tivo Roamio system in my new house. This would consist of multiple Roamios and multiple Minis. The house is wired with cat5 and coax at every potential tv outlet (10 total). Those lines all run to a large wall box with power outlets in a storage closet. My ideal setup would have three Roamios in the common areas and seven Minis in bedrooms/office. Each room that has multiple wired network devices (gaming included) would have an Ethernet switch. Now for my questions... Should I connect the Roamios and Minis all with the coax for a moca network? If so, how do I run the spitters so that all boxes can communicate with each other? Is that the more desirable setup? Is it faster? I don't want to bog down the Ethernet network with Tivo traffic unnecessarily. I assume I also connect Ethernet for Tivo guide data, web content, etc. Can I have 10 Tivo devices on one network/account? With three six-tuner Roamios I would need three multi-stream cablecards, correct? Are tuning adapters needed with the Roamios? Is there a "best way" to setup the Minis for a scenario where all 10 TV's were on and tuned to a different live TV channel at the same time? I currently have a Series 3 Tivo with upgraded storage and lifetime service. How will that work with the new system? Am I better off selling it? I am not too worried about the content on it since it's been little used for two years. Today I have a cableco DVR hooked up that says "unable to record". I don't want to waste time with it. Luckily it's a slow week for TV programming. All advice and suggestions would be greatly appreciated.
