Serviio

I have been using Serviio for several years with no problems, including numerous files with subtitles in srt files or embedded. I have suddenly found that subtitles no longer work, and this is on both an Lg tv and going through a DVR. With the tv the subtitle icon that would highlight when there was a subtitle available no longer does, and with the DVR when clicking for subtitle, it says that is not permitted. I can only conclude this has something to do with the program and not the devices. Might going to an earlier version of Serviio work? Has anyone else experienced this or have a solution?

Check to see if the profile assigned to your player(s) was changed. If files are being transcoded, that would lose any embedded captions, although the SRT files should still work. Perhaps the correct profile handles captions differently than the one it's using now. Depending on your media and what the TV supports, you could try the generic profile, which performs no transcoding.
