.SRT Subtitle Embedded in .MKV Not Displaying on Roku
I have a number of anime episodes that are not displaying their subtitles when viewed on my Roku Stick and Roku 3.
All of the affected episodes are .MKV files with embedded .SRT subtitles. Both Roku devices and the web player indicate that there are subtitles present. But they only appear in the web player.
All of these files correctly displayed their subtitles in the past, but they appear to have stopped working at some point in the past.
Anyone have any idea how to re-enable them?
