Samsung UE43J5500 + Zyxel NSA325v2 + Serviio 1.5.2 - no sub

Hello
I have Samsung TV from 2015 line UE43J5500.
On my NAS Zyxel NSA325v2 I have installed Serviio 1.5.2 + JDK 1.8 + ffmpeg2

DLNA server works fine and clear but there is no subtitles in movies.

Maybe someone solve this? For my TV I set Samsung H profile in console.

best regards,

Rafał

No subs on UE46JS8500 as well. BubbleUPnP is pushing subtitles to the TV.

How can BubbleDLNA help? I have installed it, configure it, create proxy server, I can see it on my SmartHub on the TV, browse files but no files can be played this way. Always told me "unsupported/stopped" through Proxy.

Any ideas?

Thanks.
