I just want to use plex as DVR for recording live TV from my antenna via the Hauppauge dual tuner USB device.
I have plex server active, I have my shield connected on my home ethernet network, and I have my antenna connected and getting signal via the Hauppauge tuner (I can see it's working if I test it by way of the Tablo Engine app on my Shield).
Whenever I go to https://plex.tv/web and login and try to "set up plex dvr" I get stuck on a screen that says "looking for compatible devices" and nothing ever happens from there.
One potential conflict is I'm stuck as double NAT (I live in a rural area and can't have a traditional ISP and must use a line of site dish to a local tower for my ISP and their setup forces a double NAT and I can't go into a bridge setup). If I enter the IP manually for the shield it can't find anything either.
I do remember when Tablo Engine app was starting I had to allow usb access (presumably for the Hauppauge tuner usb stick) for the app on my Shield at one point, but I've never had the opportunity to grant permission for the shield plex app to do this.
I have no VPN running on either computer or Shield. I have deleted and re-installed plex multiple times on the Shield, I have current versions of everything.
Tablo seems to be crap, and I can't get plex working, so I'm losing my cool now. Any suggestions please?
