Using TVHeadend in my media server with Hauppauge 2250 cards.

When I had Kodi v18 then sometimes the captions did not appear, but mostly they were visible.
With v19 captions were visible about half of times.
Now I run v21 and I see captions very seldom.

Yesterday I was watching a channel and captions were working, I hit the record button and recorded the stream. Now playing the stream back and captions do not appear, although I can toggle subtitles off and on, Kodi is not complaining. Then I loaded the TS file into Handbrake and recoded about 10 minutes of it. The resulting MKV file has proper subtitles from TS. Then I tried to play back the TS with MPV and it also does not display captions! 

Now you may say it is not a Kodi problem ... but what is it? I'm running Gentoo, something missing in my system? But why I see these captions sometimes then?

Edit: Has nothing to do with Gentoo, the TV set in guest bedroom has RPi with Libreelec, Kodi v21, does the same thing. W** is it?
Any ideas that might shed some light on this mystery are welcome.

Well, there must be something Kodi cannot handle in that MPEG2-TS which comes out from my Hauppauge 2250 cards. Handbrake gets it every time. I just hope Kodi developer(s) may find time one nice day and check out how Handbrake does it.

To receive meaningful assistance you will need to provide a full debug log.

The instructions are here... debug log (wiki)

If you are using the Basic Method, then ensure the following is applied...
1.Enable debugging in Settings>System Settings>Logging,
2.Restart Kodi
3.Replicate the problem.
4.Upload the log to Kodi Paste Site manually or use the Kodi Logfile Uploader. (wiki) With either method post the link to the log back here.

If you are using the Advanced Method ensure you have correctly created and applied the advancedsettings.xml file (wiki)

In both instances, you should see the word DEBUG throughout the log.

Note: Full logs only. No partial or redacted logs
Do NOT post your logs directly into the forum. Use the Kodi Paste Site. Post the link to your pasted log in the forum
