I'd like to play generally 2d 1080p mkv files with external srt files, some times mkv 3d movies, 4k is a nice to have option because of future, jukebox would be also nice.

What kind of "mkv 3d movies"? Full MVC 3D or SBS/TAB type? If latter, get nVidia Shield. If former, HiMedia Q10 Pro. Yes, Q10 Pro has some issues, but major or nagging ones should be fixed by Fall/Autumn I think.

I played until today only SBS/TAB types 3D movies. I must say I don't know exactly what is the full MVC 3D format.

You mentioned earlier the Intel Nuc player as your favorit if I good remember. It is not better than nVidia?
