Newbie here...just wanted to get an exact answer from someone that has the Roamio. Basically, I have 4 TV's total and I want to use the Roamio base model to steam recorded shows (rarely, if ever, watch live TV) to the other 3 minis. My question is this- will watching a recorded show on a mini, take up a tuner from the Roamio? I called Tivo twice today, and two different people said that it does...meaning if I had all 3 minis watching recorded shows, then the base Roamio would only have one tuner left to record new shows. This sounds stupid to me, as the mini shouldn't be using a tuner to watch what is on the harddrive, but the Tivo reps insisted this is true. What is the real life answer please?
