The P81 file helps to „repair“ not only not starting P4 files, also P7FEL and P7MEL.

Is this a consistent experience for you too that playing the P81 fixes the issues for P7 / P4 samples? What about Plex? Is the behavior same (issues with P4/P7 unless P81 is played first) there as well?

Yes, its consistent. But mostly I have to play the P81 file more than once to get the P4 / P7 samples to work again. 

I described all my findings (for example reproducable issues) and test results at Github: 

https://github.com/xbmc/xbmc/pull/18965#...-753479715

I also checked the 5 mkv test files with "Emby for AndroidTV". You can see my results in the table of that Github post. The Kodi issues weren't reproducable with Emby. Emby DV is really stable for me, even though it's not completely perfect. 

In my opinion the issues we have are dependent to Kodi and not to Android. Maybe someone who also uses Emby can confirm that. @sk83 What do you think about it? (You wrote that you also tested Emby.)
