Subtitles do no work for some mkv, I have used subtitles every time I use PMS, its amazing, love it, but now sometimes they don't seem to load at all. I've been using mkvmerge to add the subtitles to my moves and they were all working fine until lately, in some movies they just don't appear, tried putting the srt file on the folder and would not even load that, my settings have always been the same.
Can it be something on MKV file themselves? Because so far I've been doing what I've been doing for years.
My settings are on the attached pictures, running windows 8.1 64bit, core i3
