I just ordered a Roamio Plus, and a Mini. I currently have a Premiere XL4, and two Series 3 units. I have seven TVs, three of which are just connected "basic" non digital cable wall outlets. My plan is to sell the Series 3 Tivos and eventually service all seven TVs with the Premiere and Roamio, and additional Minis. My original intent was to hook up the Roamio to our main TV and the Premiere to a little used TV in the basement family room. There is a DVD recorder connected to this TV, which I use to archive programs.
My problem is that my wife has gotten used to using two tuners in the bedroom, so that she can watch two shows at the same time. She would not be able to do that with the Mini--only being able to switch between two programs in real time? So, if I connect the Premiere to the bedroom TV, would I be able to connect a DVD player to the Mini via the breakout cable, and use HDMI cable for the family room TV? Do they output simultaneously, as does the full size box?
