Thank you for your answer.
I'll try step by step over the weekend with your file and try to reproduce it with Big Buck Bunny.
The files I have are all TV episodes with cut out commercials (copyrighted material), so I'm going to transcode BBB to 25fps, demux the file cut the video and audio and remux it.
I think I then have a non copyrighted postable file with the same structure as the others.

I don't know how Kodi tries to keep audio and video in sync. I guess with 15.2 DVDPlayer "slides" the audio and now with 17.0 VideoPlayer drops frames.
Has this method changed in the actual builds? I thought CDVDPlayer/CVideoPlayer was just a name change?

I have no clue why Kodi on Android plays the files without glitches ... I'll investigate that issue further and keep you updated.
