I have my mediaplayer Minix U9 H connected to my NAS (lan ethernet cable). Using Kodi & smb I can see all my video's. However, they won't play. Sometimes I get pixeles & colours on the screen,sometimes a freezing image,sometimes no reaction at all.
Is it possible something is wrong with the connection speed? What connection speed do the LED's on the Kodi box, router(s)/switch(es), and NAS show? Have you made any changes there? A slow connection might not be noticable for browsing but certainly would viewing HD content, and in a way much as you describe. Music would probably still work OK with a slow connection, so try that, too, just to see.
