Movie with a massive audio delay

[FatMax1492]

Hmm no.. Chinese movie is AVC and 4k77 is HEVC

I did actually make an encode to HEVC and tried it. It's down to 16.4 Mbps, with passthrough audio and subtitles. The problem still persists but I did see shorter loadtimes and less cpu ussage when playing.

We can be sure it's not caused by bitrate, and probably not by codec either.
