Hello,

So I'm new to the androidtv game but now own an Nvidia Shield and Sony x950h running AndroidTV. I am also new to the NAS game. I have an NAS where I'm accessing the files directly to play on my TV (no plex server or anything like that). I have two questions:

1. How do I ensure I am getting the full 4K/Atmos quality out of the compatible files?
2. What app will let me select the dubs/subs that are packaged either in the file or in its folder?

I've used kodi and VLC so far and they play most files but I'm not sure if I'm getting 100% quality and I can't control the audio tracks.

Thanks in advance.
