Specifically, I have 3 Premieres (2 XLs and 1 XL4) on cable cards on a home ethernet network and would like to add an OTA Roamio paired with a mini: Can a TiVo mini "see" other TiVo recorded content or just the one TiVo it is paired with? Can an OTA Roamio that is paired with a mini see AND share other home networked TiVo recordings that are on cable cards/cable TV? (All would be on the same ethernet network.) Can 3 minis be used with the OTA Roamio and share content at the same time? When the mini is used to share content across the OTA Roamio from the Premiere box does it tie up a channel on the Premiere? Any other thoughts would be helpful and appreciated.
