Tvheadend

I stumbled upon a bug in Kodi 14.0 (stable ppa). I'm running ubuntu 14.04. Everything works fine, except for 6 radio channels. Those, I'm trying to listen to via PVR add-on pvr.hts 1.9.39 (installed via stable PPA as well.

It feels like a problem with KODI because playing it directly from the HDHomeRun works fine. Also playing it from TVHeadEnd in VLC works fine. I can see in the status of tvheadend that its running a stream, however Kodi keeps saying 'Buffering 0%' indefinitaly. Kodi remains response though.

I enabled debug logging and created two logs. One logs for playing 'Radio 538' which works fine, and one for 'NPO Radio 2', which doesnt work.

Radio 538, working fine:

Last variant I tried is manually tuning the HDHomeRun to Radio 2 and then picking up the stream as hdhomerun device in Kodi, that works fine:
