In the past this has not been a problem, but recently my Shield TV will only show my subtitles if I set burn subtitles to "Always".
The subtitles are in an external SRT format. I have had no trouble with them on other plex clients i.e. the Web or my Android phone. What I mean to say is that on any other device, I can set burn subtitles to "only image formats" and they work. It is only on the Shield that I must set it to "Always".
