    I just tried a 2 channel movie as a source and it worked
    immediately, including the audio.  The described "stretching"
    effect only happens when using a movie with a single channel.

    Should not the PCM track format for 2 channels be the same,
    regardless of how many channels the source had?

    Using this cmdline now:

        mencoder "$in" -o $out -ovc libdv -oac pcm \
            -vop scale=720:576 -ofps 25 -srate 32000 -channels 2
