I have a Series 2 40 Hr which I know has only one tuner but here is what it did last night. I was watching and recording House on Fox (Season Pass 9PM-10PM) at the end it stopped recording and remained on Fox. I also have a season pass for Boston Legal which is scheduled to begin recording at 10:01PM so at 10PM Tivo asked me if I would like to change channels from Fox to ABC to begin recording Boston Legal. I hit OK and at 10:01 my Tivo recorded Boston Legal but the channel I was watching remained on FOX as if I had 2 tuners. Anyone out there ever see this before?
