I have UE49MU6100UX with Emby client installed.
For now I've encountered strange problem several times. For some reason Emby Smart TV don't show episodes in the series season. But if select "Play All" or "Shuffle" in the season screen - some of episodes will start playing. I didn't determined if it's related to certain shows and happens every time or it's just happens for them sometimes and goes away. But at least now I can't see episodes from "Sword Art Online" season 1 and 2. At the same time I can see episodes of "Avatar: The Last Airbender" show in the same library.
I have a bunch of series episodes of which I can see and a bunch of series where I can't.
At the same time Android app and web interface are showing episodes perfectly.
