I just finished my setup with a roamio plus & 3 minis all hooked up via 6 cable & 4 trendnet "green" switches. Everything works great and actually was approved by the wife. i got rid of 2 premieres using 2 cable cards which will save $9.00/month. I have several questions regarding the minis. i notice a slight delay when channel changing versus channel changing with the roamio. also is there any way to activate the live tv window when pressing the tivo button. I get live tv when pressing the guide button but not when pressing the tivo button. Lastly, the mini is actually a one tuner device. I cant switch back and forth between tuners by pressing the live tv button. any help is appreciated.
