I just purchased a LG 55UH6090 4k web OS 3 television. I connect to my Plex media server via wifi network and using what I believe to be Smartshare everything appears ok. All my video folders show up properly. All the video files inside these folders show up normally and the video plays with no problem. Unfortunately the subtitles do not display. It detects the subtitle track since the sub icon is not grayed out. I've toggled the icon on and off multipke times and subtitkes do not appear. Playing the same video file via USB connection produces the same result. Video and audio but no subtitles. The video is a .mkv file with embedded subtitles. This same file plays 100% correctly through my Samsung smart tv, Samsung bluray player and my WDTV live hub. It plays properly via USB and wifi from Plex media server. Only device which has a problem is my webOS 3 tv from lg. Any ideas? Thanks
