Can't see video files Samsung 7 series

Hi,
I'm trying to connect my Linux PC (Debian 8 Jessie). My TV is Samsung UE48JU7000. I've started the serviio server and select to share two folders - one with videos and one with pictures. The TV have access to the serviio server and I'm able to see the pictures. But when I open Serviio -> Video -> Folders - My Videos (This my shared folder) the folder is empty. On the computer in this folder there are avi and m4v video files and subtitles.
I can't see Samsung 7 Series in the profiles, but try with other Samsung profiles. Also configured the router to enable Multicast Streams.
Can you help me with this?
