        In the MPlayer documentation hierarchy you'll find a file in
        DOCS/tech called encoding-tips.txt

        In that I see that the "-audiofile" option is valid with 'mencoder'

        I think that means you can use an external file to supply the audio
        thusly:

            mencoder -audiofile out.mp3 -oac copy ...

        just prepare the .mp3 or whatever ahead of time and use that.

        As an experiment you might try doing a one pass encoding to compare
        against the results of a 2 pass.  It might be possible you don't
        see much, if any, difference and can thus save a lot of time.

        Cheers,
        Steven Schultz
