Hello, I have an iusse ussing subtitles on streaming channels.

I have a enigma2 STB server to stream on LAN to another devices, the problem is that subtitles only works on PC or Android devices, according to the following scheme:

Enigma2 STB -> PC, subtiltes working with VLC
Enigma2 STB -> Android, subtitles working with DreamDroid
Enigma2 STB -> Enigma2STB, subtitles not working

I have installed openATV 6.0 on STB client and converted m3u file to bouquet. The strem works and I can select audio channel but subtitles not work. The service has the follow service reference:
#SERVICE 4097:0:1:29:0:0:0:0:0:0:http%3A//

I would apreciate any help.

Kind regards.
