Well, 2, really...
This is the text on the TiVo website today:
TiVo Roamio DVRs allow for dynamic tuner allocation, so the tuner is only used when the Mini needs it and is released back to the DVR for use when the TiVo Mini isnít in use. TiVo Premiere DVRs do NOT support dynamic tuner allocation, so any Mini connected to a Premiere is allocated a constantly dedicated tuner and therefore reduces the tuners available for the Premiere DVR.
I thought that DTA was going to include Premiers? (I have an XL4). So, it doesn't, will adding a Mini turn my XL4 permanently into a 3 tuner system?
Next question (same really, just rephrased), if I don't ever want to use my Mini for live TV, will it still turn my XL4 into an XL3?
Confused in CA.
