Teletext is not working if running in M3U-playlist mode

[Sopor]

Teletext (dvb_teletext) is not working if i set "Content source" to "M3U-playlist". If i change it to "Web portal" or run it in VLC it works. It is not a bad stream because I have tested several streams that have teletext and none of them are working in M3U-playlist mode.

When a channel has "dvb_subtitle" it works in M3U-playlist mode.

I'm running firmware 4.2.35 on my TVIP S-box v.610 (S610).

It should be work if subtitles inside the stream

There are more than one subtitles to choose from and i can even turn them off if i want to, but even if i cycle through the subtitles (green button) none of them are working. I have now updated to 5.0.7 (25.08.2020) beta, but still no dvb_teletext subtitles.
