So what happens is this. I start a video of any kind. In this case a 1080p Blu Ray. I finished the video. to the end. Then I started the debug log. Issue:

I start playback of the next video. Kodi seems to freeze for a while. Then it starts buffering…video starts at some point. And then the video goes black and stops. Happens every time on the 2nd video. Then I start the video again, and it plays…

Why does it happen?
I see a lot of: error : timed out while waiting to receive (500 ms) (For accessing my SERVER that is coming out of sleep. But the video is not located on that SERVER. It’s located on a N100 always on MiniPC.
And I see this a lot: debug : CVideoPlayerVideo - video decoder returned error

Any clue to resolve this?
