It's sad that if you really LOVE the Wonderfully Developed Live Guide and you Like to Push things up to the Tivo from a PC, it is Not Good. If you "upgrade", then you have to put up with the STUPID Back Button (what genius thought of that?) and whatever ridiculous other crap and bugs. Look how long it got for TE3 to be fairly good. Not enough updates in my opinion, being it is such a "new" "experience"...LOL
But then you gain NO AUDIO delay coming in and out of TC and supposedly it is a bit snappier (not totally convinced about that on a Roamio) and Voice Command.
Now I forgot a lot of how the boxes connect together. So I know a Mini that is tied to a TE4 host must have TE4 on it. What about my XL4? That does not run TE4, right? So I would still be able to Push to it? And then be able to transfer to the Roamio if I want? But then the Mini could not play anything from the XL4, right? But the TE4 Roamio could play from the XL4? It's all so DUMB...

Wish I had a spare Tivo host to test with, but I don't...Oh well, my prediction was always Xmas 2019 for it to MAYBE get better...
