I have problems with a few of my HDR movies/shows. It almost always start with a lot of stutter and after a few seconds plays smoothly. Then it can run just perfect for sometimes a long time, like 20 minutes and suddenly start to stutter for a few seconds, play for 10 seconds and stutter again a few seconds and then continue to play fine for a long time again. I cant see any connection to h265 vs h264, same pixel depth and frame rate or bit rate since a high bit rate 4k hdr plays fine but a pretty low bit rate 1080p file sometimes behaves like this. So here’s no clear pattern from what I can see. Any idea how to start troubleshooting?
Plex plays everything just fine.
