Infuse 5 playback

Im having problems playing movies on Apple Tv 4 using InFuse 5… The picture is frezing/stops a bit once in a while?

I have i Synology nas 415Play, and never had any problems…

What type of videos are these?

MP4, and MKV…
Maybe its my new 65" Philips Tv? :frowning:

I just dont have the problems when playing Netflix, HBO etc …
Is it a buffering problem maybe?
