Ok:
All players and codec packs uninstalled.
SVP installed with MPC-HC, FFDShow and AviSynth, without Haali
LAV Filters 60.1 installed.
Results:
All video codecs works fine.
Audio and subs tagged as default (from mkv container) works fine.
Subs from external file works fine.
In Soundtrack context menu is only one track named Audio, and subs menu is inactive, player "doesn't see" another soundtracks, any soundtrack names and any subtitles - subs menu inactive even if default subs are displayed.
No "media info" in explorer context menu.
So, you're right, HEVC works good, thanks for it, but there are another problems. Only default tracks works as they should, and I don't wanna repack containers to watch movie as I like to.
