Let's see:
- mplayer-doc/HTML/en/menc-feat-mpeg4.html : example shows same 
  audio parameters but does not mention that it's mandatory
- mencoder(1) divx4 pass and vbrpass parameter: nope
- mencoder(1) lavc vpass and vbrpass parameter: nope. Even worse,
  we're told to disable CPU hungry options. It's *really* tempting to
  apply this advice to audio encoding (why encode audio twice ?)
- mencoder(1) xvidenc pass: nope.
- mencoder(1) x264 pass: nope.

Since maplyer man page is HUGE, it's still possible that I missed this
information somewhere, but I doubt it.

Like "The Wanderer" suggested, it should be possible to store the
first pass command line in the log file or in another file.

I mention "should" since I do not know the architecture of mencoder.
