Plex, subtitles, .ts file from DVR

Server Version#: 1.41.0.8994
Player Version#:7.26 build 14
symptom: no subtitles from dvr created .ts file when using plex on roku devices (ultras 3 in home). Windows player, web player, Firestick, chromecast TV dongle all play captions normally. The video is ‘Opry live’. Playing on VLC I have to select sub track Closed captions 1 to display subtitle/captions. Other shows recorded do display captions and those shows on VLC have same cc1 captions.

had to add details sorry for the nearly blank original post
