I've looked over the forums, and tivo.com, regarding the TiVo Mini and TiVo Stream, which only left me with more questions, so I'm hoping someone can help me piece all this together. What would be the best solution to get my 4-tuner Roamio to have the same capabilities as my Roamio Pro & Plus, in streaming programs between them all via "Play" rather than the old multi-room transfer/delete, as well as outside the home via Tablet/Smartphone? The easiest solution would be to just just replace the 4-tuner Roamio with another Pro or Plus, as it's all built-in to these, but I want to keep the 4-tuner Roamio for its OTA ability as backup for when cable is down, and still be able to stream programs between them all; that is, start in one room and finish in another, via "Play" rather than transfer/delete. Currently, I can stream programs between my Roamio Pro and Plus, as well as stream from my 4-tuner Roamio to my Pro and Plus, but I cannot stream in the reverse, that is, from the Pro or Plus to the 4-tuner Roamio, I have to transfer/delete to the 4-tuner Roamio; i.e., I can stream from the 4-tuner Roamio to the others, just not to it. Thus, would just getting one TiVo Mini allow me to stream from the Pro/Plus to the 4-tuner Roamio as well? And from looking at the install directions, would I just install it to any TV by itself, or does it have to be tied to the 4-tuner Roamio somehow, physically or through settings? Plus, I am able to stream between the Pro and Plus without MoCa, via WiFi; my Pro is on Ethernet, the Plus and 4-tuner Roamio on WiFi. But I'm reading the Mini needs MoCa or Ethernet, no WiFi, so if I connect the Mini to an open HDMI on my TV in the living room and an Ethernet port on my router, while my 4-tuner is connected to a TV in my bedroom via WiFi, will this allow for program streaming in all directions between all three of my TiVo's? Or would I still have to create a MoCa network, I'm presuming thru the Pro? Or does the Mini somehow have to be physically connected to the 4-tuner Roamio? Would all TiVo's then have to either be MoCa or Ethernet? Currently I am able to stream between the Pro and Plus via WiFi. Then, after all that is achieved... would I need to get a TiVo Stream in addition to the Mini in order to stream programs from my 4-tuner Roamio outside the home, as I can currently do with the Pro and Plus? Thank you!
