This works for me:

#!/bin/sh

DEFBITRATE=1150

#if the first argument is an integer, then it is BITRATE
x=$1
case $x in
*[!0-9]*)
#echo It is not an integer
;;
*)
#echo It is an integer
DEFBITRATE=$1
shift
;;
esac

for ARG in "$@"; do

# check BITRATE from source (VMW doesn't have this info)
BITRATE=$DEFBITRATE
aux=`mplayer -vo null -ao null -frames 0 -identify "$ARG" \
      2>/dev/null | grep -e ^VIDEO`
if [ "`echo "$aux" | awk -F " " '{print $8}'`" = "kbps" ]; then
   aux1=`echo "$aux" | awk -F " " '{print $7}' | awk -F "." '{print $1}'`
   aux2=`echo "$aux" | awk -F " " '{print $7}' | awk -F "." '{print $2}'`
   if [ $aux1 -eq 0 ]; then
     aux1=$DEFBITRATE
   else
     BITRATE=$aux1
     if [ $aux2 -ge 5 ]; then BITRATE=`expr $BITRATE + 1`; fi
   fi
fi

nice -n 19 \
mencoder "$ARG" -of mpeg -o "${ARG}.mpg" \
-vf pp=de,harddup,softskip \
-ovc lavc -lavcopts vcodec=mpeg2video:vhq:vbitrate=$BITRATE:autoaspect \
-ofps 25.0 \
-oac mp3lame -lameopts br=128:q=9:aq=9:cbr:mode=1

done
