DVDFab file to mobile (mpeg4) audio issue

When trying to convert a 23.976 fps, 720p MKV to a lowres mpeg4 video file the audio gets all weird, serious sync issues and the audio in the beginning of the file seems to play way too fast (using VLC).

You might try posting this on the Fab Mobile sub forum. Many knowledgeable, helpful people thereā€¦
