I reported this over in the music section, but its buried in a thread about mka file tagging and progress bar issues. Best this has its own thread:

ISSUE:
Kodi 18.3: Music Videos from DVDs (NTSC and PAL) are way out of video/audio sync. In fact the video appears to play in slow motion. These are MKV videos with DTS or AC3 sound. The same MKV files play correctly on Kodi 18.2. (and all previous Kodi versions since Kodi 15 when I started using Kodi)


NOTE: All above tests on Kodi 18.3 on Intel NUC with LibreElec (LibreELEC-Generic.x86_64-9.1.001)

I solved the problem.

I had my 4K TV and I'd set the Kodi interface to 2160p 24Hz. I've switched it to 1080p 60Hz and all ok.

I have the player set to Always sync screen to video, seems it couldn't sync the screen to NTSC or PAL video sync rate which is higher than 24Hz I'd set in Kodi.
