[HELP] Hybrid introducing audio delay that is not present in source material

[protectron]

Okay, for mp4 please try whether it works in ffmpeg without having to disable the delay adjustment.
Enable 'Config->Container->Mp4 Settings-FFmpeg instead of MP4Box' before creating the job queue.

Actually I may have spoke too soon - with further testing it seems like nothing I do can change the audio delay, even manually.

FFMPEG and MP4BOX have the same result. The audio is always just slightly off.

I set the delay to 500ms for giggles and it did not change the output file. 

I checked back at the MKV output and it was off as much as the mp4. 

Debug is attached. In the link is a sample out-of-sync output. Slowing it down to about 40% in VLC helps. The source is dead accurate.
