Hi there @Tolotos,
I'm trying to get LiveTV on my devices but it doesn't work with any of them.
TVH is connected and seems to be OK.
I'm using OMV with HTS Tvheadend 4.0.9-16~g63c1034~jessie with the actual plugin and Emby-Server Version 184.108.40.206.
I do get EPG but no video.
In the attached log I tried to play livetv within my browser and on my Sony TV.
I also tried it on my chromecast ultra but also no success.
A week ago I tried the inofficial vdr-plugin which at least showed a video on the chromecast.
Any ideas ?
