When I sample that talk on youtube, I only hear occasional clipping.
Mostly, the audio is very good.  

I don't know about doing it in mplayer, but you could strip the audio
with ffmpeg (or mplayer -dumpaudio), use audacity to lower the volume
(amplify adjust or normalize, maybe some compression to make it more
uniform), and then recombine the video and audio with ffmpeg.
