oops. changed bitrate to 981

// last try, something wrong with aspect, so setting manually
mencoder -vf crop=:460 -oac copy -ovc lavc -lavcopts vcodec=mpeg4:vpass=1:aspect=16/9:vbitrate=980 -o movie.avi *.VOB


-- again

// crop if necessary
mencoder -ovc frameno -oac mp3lame -lameopts vbr=3 -o frameno.avi -mpegopts format=dvd *.VOB
