Streaming to Mini via ethernet is flawless. Same quality as if I had a cable DVR with boxes on other TVs. I don’t watch much via iPad, but my wife does. I have not heard any complaints. As for streaming over the internet I have only done it a few times and it work OK enough. Definitely better remote over Wifi.
Also, Tivo integrated Netflix and Amazon Prime video work great. Like having all content via one unit (same as Tablo).
FTR, I don’t come back to bash. I truly want Tablo to get better as it is a much more economical than Tivo. I will consider switching once it gets closer is quality and speed of Tivo. Based on the issues that I had last year and it seems like others are still having, I am thinking the current HW is not robust enough. Which is weird because the unit is not cheap considering you need an external HDD.
