That obviously is a non-interleaved file. There are a rare few occasions
where it makes sense, but usually it's a sign that whoever created those files
was incompetent.
I think you can set MPlayer options in the config file based on extension,
which might help here if it works.
Other options are
- using mplayer file.mp4 -audiofile file.mp4
- remuxing the files to be properly interleaved (I would guess MP4Box or similar
  software could handle that).
- optimize MPlayer's cache to handle this case better
