Tvheadend

Hey guys!

I'm running LibreELEC on a Raspberry Pi 3 with TVHeadEnd HTSP as the PVR-client.

Been reading a lot and there seem to be a problem world wide that the picture is freezing when switching channel but the sound continues of the switched channel.
The only thing that can be done in this case it freezes is to press the STOP-button and reload the channel. Then it works again.

The problem doesn't happen all the time ... just sometimes like 5 cases out of 10.

This seem to be a known problem for the PVR and is there somebody out here who got a clue of an solution of the problem?

Thanks!
