[HELP] "Real" PAL<>NTSC framerate conversion with speed changing?

[DannyHicks]

This happens if Hybrid for some reason things it needs to use ffmpeg for multiplexing, problem is FFmpeg on passthrough doesn't rewrite the stream&container fps, which is why Hybrid aborts in this case.
For mp4 ffmpeg should not be used unless specificly forced by the user.

It happens with both MKV and MP4. 

I also tried AVI and MOV. Same error.

Is there a way around this? I don't remember setting something that forces ffmpeg to be used.

EDIT: I reset all settings to their defaults, but that didn't make a difference. I still get that error, despite the fact Config>Containers>Mp4 Settings>"FFmpeg instead of MP4Box" isn't even enabled. And I also don't see other settings that make a difference when disabled.
