Server Version#: 1.21.4.4079  
Player Version#: 5.9.1

Ps4 App always force transcoding Video if Subtitles are activated. (Embedded, External and Online Subtitles) on MKV Files.

Audio Formats i tested AC3, DTS, DTS-HD MA, AAC  
If subtitles activated Audio goes Direct Stream and Video Transcodes  
If subtitles deactivated Audio goes Transcode and Video Direct Stream

On my slower DS218+ Synology NAS this cause Video buffering because Hardware to slow for Transcoding Video on 1080p.
