Buffering issue in Krypton

Hi, I am using Krypton in LibreElec 8.0.0 on a Wetek Core and this device has a wired connection to my local DVB link server. Until now I had a steady connection (last 4 years of live TV streaming) without buffering issues. Like I sed until now….
In Kodi 17 I seam to see an issue when trying to play live TV streams. In most cases the stream opens but not in all cases…for Nederland 2 for instance it keeps buffering and wont start. Beside that once a stream is playing every now and then it needs to buffer a fraction of a second.

Anyone else knows what is causing this issue?
