I was talking to my neighbor about my current TiVo setup where I just added a TiVo 4 and Mini to my house. I described how it works that the Premiere 4 basically dedicates a tuner to the Mini. He asked if he bought a Premiere 4 and 3 Mini's how it would work. MY understanding is that in this configuration, the Premiere 4 would only be left with 1 tuner to use for watching shows or recording. Is that correct? Thanks!
