The original sound track sounds fine ( mostly spoken voice ).

I've don't have any publicly accessible space to put the clip but here 
is the command I'm using:

mencoder -oac lavc -ovc lavc -lavcopts 
-of mpeg -mpegopts format=dvd -vf scale=720:480,harddup -srate 48000 -af 
lavcresample=48000 -ofps 30000/1001 -o aribday.mpeg aribday.wmv

This line was actually generated from a shell script I've just started 
to write.


LAVC="-oac lavc -ovc lavc"

VIDFILTER="-vf scale=720:480,harddup"
AUDFILTER="-srate 48000 -af lavcresample=48000"
MPEGOPTS="-of mpeg -mpegopts format=dvd"
OFPS="-ofps 30000/1001"


"$DEST" "$@"


The only thing changed from the HOW-TO is the aspect ratio ( from 16/9 
to 4/3). I've also tried "-ofps" of 24001/1001.
