(Sorry for the length, but this problem has become complicated, time consuming, and expensive.) We’re considering a TiVo Bolt OTA plus four Mini Vox units, but need to be certain we do not replicate an annoying problem. Our kitchen overlooks a family room on the main level. With a DirecTV DVR and DTV minis, our TV’s were not in synch. People would cheer in one room before those in the other even knew what had happened. Same problem upstairs and downstairs. Audio and video at individual TV’s were in synch, but not among TV’s. DirecTV decided that the synch problem is a design/technical issue, not an installation problem, so they thankfully waived the early cancellation fee. OUR ENVIRONMENT: · Internet is slow but a consistent 10 mb/s. We have no hic-cups watching 4K movies from Amazon Prime Video. Could change to faster broadband if necessary. · Our 802.11n router is on the 3rd floor but we have a good signal on all floors. I think we can relocate it if necessary. · All of our TV jacks are tied into the main level family room equipment via coax. QUESTIONS: 1. Will we have an out-of-synch problem among TV’s with TiVo, if all TV’s are using TiVo devices? 2. Does it matter/recommended if the Bolt is wired into the router or wireless? 3. Does it matter/recommended if the Mini’s are connected to coax or wireless? If you do not know the answers, do you know where I can research the topic? Thank you!
