Thanks for replying. I'm sorry I forgot to mention that I downloaded that video from this website. It has DTS:X audio and my AVR had no trouble playing it.I think your English is perfectly fine the only issue is that Youtube doesn't support anything other than plain 2.0 stereo, so are you 100% sure that that video even contains DTS:X? It's plain 2.0 stereo here.
Perhaps I have mis-read, because you use the word emulation, so you know that it's just a 2.0 soundtrack and it's relying solely on the AVR's DTS Neural:X up-mixer.
