Apple tv 3 new won't play videos or photos

Hi guys,
Recently I found problem with my apple tv 3 which give me error on video playback and not showing photos in my photos app unless I turn on screen mirroring.
Before it I used to play movies with infuse app in background playback mode without any problem. But from iOS 10.2.1 public release and now that I'm on iOS 10.3 beta 1, I reached this problem.
I don't know this problem caused by iOS or not!
I forgot to mention that musics play without any problem through airplay.
The error I get on video play back is in attached screenshot, on photos I got no error but nothing shows on tv screen, just home screen of my apple tv!
Anyone knows anything about this guys?

 

Any idea?
