Embedded ASS subtitles in MKV DirectPlay support

Hi guys,

I have hundreds of 1080p HEVC movie files.
Talking about the actual PMS (1.3.3) and the actual players Plex Web and on FireTV 2nd gen… (the ones I can test), embedded ASS subtitles within an MKV container result in either Plex not playing the movie at all (generating an error message) or stuttering (1080p, HEVC) playback which makes the movies unwatchable.

I could wade through the movies and extract the embedded ASS to SRT, but I guess that it cannot be all that hard to support embedded ASS subtitles and direct play these movies in a feature update.

I would be SO GLAD to have this being supported. It would spare me from lots of work.

Thank you very much.
