OK, I'm probably asking a stupid question now that I'm about to become a Roamio Plus newbie... During my various areas of research on the boards I occasionally come across posts were people talk about having two Roamio's for their home. If a Roamio Plus (like I'm planning to get) has 6 tuners, why would you need two of them, unless you plan on watching/recording more than 6 shows at once. Is is that simple? I plan on a Roamio plus and 4 mini's? Would there be any reason for me to consider two Roamio's and 3 mini's? Straighten me out!
