Ac3 is fucked up in plex on mi tv currently.

It works like Plex does on Android TV. Are you looking for codec support? 'Cause I've been impressed with how it is able to direct play most of what I've thrown at it. If you want me to test out a particular type of media, let me know and I'll give it a shot. I'm going to download Big Buck Bunny 60fps 1080P and 4K and see how it works out.
