I just noticed this the other day surfing around in settings - Settings & Messages> Settings > Remote, CableCARD, & Devices > Allow Live TV on Other Devices http://support.tivo.com/app/answers/detail/a_id/2395#instructions To me, this is actually BAD NEWS. I have a P4 and sometimes actually record 4 shows at once! What's it's saying is - if you add a Mini - you're going to lose a tuner permanently - unless you like going to the host Tivo and changing the setting temporarily every single time you want to also use the Mini - (or if you want to record 4 shows). RECORDING ON THE HOST TIVO SHOULD TAKE PRIORITY over any other devices IMHO, and cut them off as needed - at least as an OPTION!!!!! But that's not an option - Add a Mini = Lose a tuner - is your only option. That's a deal breaker for us - we won't be buying a Mini now.
