Maybe use mencoder to encode to XViD or mpeg4 and use the settings to
normalise the audio, or to increase volume during encoding.

Maybe use '-oac mp3lame -lameopts fast:preset=standard:vol=5', but
could experiment with the settings. Vol is the gain and has range 0 to
10, where I imagine 0 is no gain.
