With my Samsung Smart TV in the living room, Serviio works fine. I can browse my media and play everything fine. On the blu-ray player in my bedroom, I only see the folders -- there is not a single file listed when I browse. Serviio did not properly detect my blu-ray player, so I selected the "Samsung TV / player (J-Series)" profile, but this didn't help.
I'm able to play Netflix using this same player.
