This is a HUGE chunk of my library - zero issues here.. Just saying..   Maybe whatever issues your running into is because your not doing hardware transcode - your player has problems with the subs? Also being direct and again your having issues transcoding? I was under the impression that subtitles inside an MKV cause transcoding and therefore I must ensure it is always an external .srt and even then set to only image formats    There s an SRT inside the MKV but when I play it in Plex, it simply knocks me back to the homescreen or even crashes Plex, this is even more with HDR content. The same content plays just fine if I disable subtitles, but as I am a little deaf I prefer to have them always enabled, in fact it is the reason I am rewatching a lot of old shows
