I am having random issues playing mkv movies from my plex server (core i5, 16gb) to my 2016 LG smart TV (WebOS 3). It will play for a while and then I get the 3 dots buffering and then off it goes again. This seems to have been a fairly recent thing.
Plugged into the same TV I tried a borrowed amazon fire stick with the plex app and this works fine with no buffering issues.
I tried the built in DLNA player in the TV and this will also play back the movies fine (but the UI sucks).
Is this a recent TV / plex app update that is causing this? Anyone know of a resolution?
