I NEVER watch pirated movies.
The Smurfs 2 (the EXACT version you mentioned, ;-) ) plays impecably on my Q10 Pro, custom firmware from pcristi, version 2.0.3 repacked from may.
I repeat, beautifully played, 2160p, HDR, I dunno about Atmos since I listen to stereo speakers.
But it opens and plays flawlessly.
So, I suggest this firmware... http://www.mediafire.com/file/5jcsl6m651f8dd9/update_Q10Pro_%28update%26themed%26Kodi17.2RC1shitty%29_HMD-2.0.3_2017-04-12.095905.zip
You do not know what you are saying. You did not buy himedia q10 to read all the movies downloaded from the web in 4k mkv ?? They are all pirated movies or upscaling or 4k capture. If you wanted to read only original disc 4k you could buy a simple reader for 4k not himedia q10
IT WAS A JOKE, A METAPHORE. I EDITED THE POST AND DELETED THIS JOKE, FOR NOT ALL PEOPLE UNDERSTAND JOKES.
YOU GUYS SHOULD LEARN TO SMILE ONCE IN A WHILE. Even if English is not your native language.
Of course I downloaded and collected all (ALL) captured 4k/HDR movies so far. I have 12TB of 4k/HDR movies and TV Series.
SO I KNOW EXACTLY WHAT I AM SAYING, it is just that I expressed it in a way that you just did not understand, my bad, appologies.
For the last time now this is my message to you - YOUR MOVIE PLAYS PERFECTLY ON MY PLAYER. Custom 2.0.3 F/W. I HOPE YOU UNDERSTAND NOW.
This is my last attempt of helping you on this topic. Hope you understand this.
