I got the latest Roku update on Jan 7. Subtitles no longer display with many of my videos. Even those I've watched 2 or 3 times previously. Strangely, some still work. The update only affected videos streaming from my NAS via Roku Media Player. All videos in question have the same .srt file associated with them that worked when last viewed. Again, not all videos are failing to show subtitles. Netflix and Prime subs are fine and the problem started after the update took place. Anyone else experience this problem? I'm going to start looking at mediainfo to see if it has to do with a specific type (MKV,MP4) - any help is appreciated.
