No subtitles - Samsung JS9000 and JS9500

[ewokuk]

I have a new Samsung JS9500 TV and simply cannot get any subtitles to show at all from mezzmo 4.1.3. The TV is obviously not in the device profiles list so I have chosen "Samsung H (UHD)" which I assume is the closest match being the previous Samsung models from last year. However No matter what I try, nothing appears on the TV (the video plays fine but no subtitles at all). The subtitles all play fine on the pc using SMplayer and VLC. The subtitles are in SRT format and I have tried right clicking on the video file in Mezzmo and adding/removing/converting the subtitles to a different format but nothing works.
