TiVo has just opened a v9.1 software update priority page, so drop off your TiVo Service Number (TSN) if you want in. However, those of you with Series2 units should keep in mind:
For Multi-Room Viewing to work in software version 9.1, your other DVRs must also be running software version 9.1. Please sign up all DVRs on your account and have 9.1 installed before attempting to use MRV.
Other than the updated Boolean Wishlists, there’s not much in the way of functional changes. Though… Megazone speculates that the relevant bits for TiVoToGo and Multi-room Viewing on high-def TiVos are in place. All it may require is TiVo flipping a switch on their end. Sounds reasonable to me given the timing of this software rollout and TiVo’s November target.
