It's been reported that you can buy a 4 tuner Tivo, connect a Mini to it, then disconnect the 4 tuner Tivo to gain the capability of using the Mini in a household of 2 tuner Premieres. I'm soon to be OTA only, and I have two 2-tuner Premieres and an TivoHD lifetimed. Using the Mini for streaming from 2 tuner boxes is of interest to me. Have you tried it? If you did, how long have you had the 4 tuner Tivo disconnected? Besides not being able to hijack a tuner to watch live tv, have you noticed any issues?
