I just want to share something, I found the holy grail of media players for everyone that wants to have maximum control and maximum image quality.
I an dumbfounded after learning that my appleTV had a lot of shortcommings in every way, dolby vision mapping is lacking and there is no true dolby atmos playback either!!
Thing is called the zidoo Z9X, its android based but its like insanely customizeable, select your own dolby mapping, turn off/on anything its like going from imovie to Flame.
I have tears in my eyes, I love this thing its the best thing eveeeer.
