I am not sure if I understood your question.
But when I want to fix the aspect ratio of an avi, I use this script:

#!/bin/sh
# Author: Paulo Roma
# Changes the incorrect aspect ratio from avi files.
# $1 is the name of the file to be converted without extension.
# $2 is the aspect ratio.

if [[ $# != 2 ]]; then
      echo "fixaspect.sh [file] [aspect]"
     exit 0;
fi

mencoder "$1".avi -o "$1".asp.avi -oac copy -ovc copy -force-avi-aspect "$2"
