I have used the 2-tuner Tablo OTA DVR for a couple years. I just got rid of a cheap Chinese android box (which connected to the Tablo just fine), and installed an Nvidia Shield.
It will NOT see the Tablo, even though they are on the same network.
I have reset the Tablo, reset the modem/router. Cannot get the Nvidia to see that there is a Tablo there.
I also have an Apple TV connected to that TV, so we can watch OTA broadcasts and recordings, but it is problematic. I can see the Tablo from computers on the home network, and from my phone and iPad.
Can anyone help me?
