I created a log with debug logging on and also video component logging.
I played my rip of The Wolf of Wallstreet in “play main movie” mode, so no Java menus or anything.
I started the movie and skipped to the next chapter → Audio out of sync and video has stutters.
Then I jumped back 1 minute → Still the same issue with audio and video.
