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 
vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=5000:keyint=18:aspect=4/3:acodec=ac3:abitrate=192 
-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.

<script>
#!/bin/bash

LAVC="-oac lavc -ovc lavc"
LAVCVIDOPTS="vcodec=mpeg2video:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=5000:keyint=18:aspect=4/3"
LAVCAUDOPTS="acodec=ac3:abitrate=192"
LAVCOPTS="$LAVC -lavcopts $LAVCVIDOPTS:$LAVCAUDOPTS"

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

DEST=$1
shift

#echo mencoder $LAVCOPTS $MPEGOPTS $VIDFILTER $AUDFILTER $OFPS -o 
"$DEST" "$@"
mencoder $LAVCOPTS $MPEGOPTS $VIDFILTER $AUDFILTER $OFPS -o "$DEST" "$@"
exit

</script>

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.
