DVB subtitle stream not recognised and ignored

[priitv8]

It seems the DVB subtitle issue has been raised already in 2020 and closed as resolved https://github.com/justdan96/tsMuxer/issues/374 but the core issue is still not resolved. I try to open a .ts file recorded from a satellite. It contains subtitles in DVB format. Unfortunately, tsMuxeR is not able to recognise the subtitle stream and will not (re)mux them into a new file. Could the DVB support be added to tsMuxeR, please?
