Up to ten TiVo Minis can be supported by one TiVo network containing TiVo BOLT, Roamio or Premiere DVRs. One tuner is used each time a TiVo Mini is being used on the network. Therefore, depending on the number of DVRs and tuners you have available, you may not be able to have all ten operating simultaneously.
TiVo BOLT and Roamio devices 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 isn’t 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.
TiVo Mini does not have a tuner or hard drive, and does not need a CableCARD. Additionally, the remote in the TiVo App cannot control TiVo Mini.
