I installed a new instance of plex server and live tv works great. Is there a way to fix the original server without having to reinstall the whole server again?
I am sorry, I am unable to help. I am having the same exact issue. I initially couldn’t get the tuner to work. Finally got it to work by installing Ubuntu 16.04, but now I can’t get past the tvxml error. I live in Albuquerque, NM. But even when I tried to enter an LA zip code, I got the same error as you posted in the title. Hoping by replying, we might get some support. I can’t even move past this to see Live TV.
