I would strongly advice to try mencoder with something like :
#!/bin/bash
Q=800
q=96
MENCODER="nice -n 19 mencoder"
if [ $# == 0 ]; then
echo "usage: $0 source"
exit
fi
if [ $# == 1 ]; then
mplayer -xineramascreen 1 -vo x11 -vf cropdetect $1
echo "usage: add w:h:x:y for cropping and 4/3 or 16/9"
exit
fi
if [ $# == 2 ]; then
echo "usage: one should have added w:h:x:y for cropping and 4/3 or 16/9..."
exit
fi
if [ $# == 3 ]; then
w=`echo $2|awk -F ":" '{ print $1 }'`
h=`echo $2|awk -F ":" '{ print $2 }'`
calcbpp.pl "$w""x""$h" $3 $Q 25
echo "usage: add x:y for scaling or -1:-1 for not scaling"
exit
fi
if [ $# == 4 ]; then
mplayer -xineramascreen 1 -vo x11 -vf crop=$2,scale=$4 $1
echo "usage: add file name destination"
exit
fi
if [ $# == 5 ]; then
rm -f frameno.avi divx2pass.log

Well, no idea what WMP is, so...

Bouah... no : aac for audio... and x264 for video :-)
