I have a 4-tuner Premiere in my setup. Its located in our main bedroom. Now that the Mini has dynamic tuning, I was thinking of getting one to add to my system. I would then like to move the 4-tuner Premiere to the living room and put this mini in the bedroom instead since I have heard its interface is faster (& this is where we tend to watch TV more). Will the Mini be significantly faster even with an older Premiere as its main hub/source for the tuner & recordings? Does a mini work faster with a Roamio in the mix compared to a Premiere or does it not matter? Just curious.
