addendum: mencoder inputfile.mpg $1 -oac copy -ovc lavc -of avi -noodml -vf pullup,softskip,scale=960:544 -ofps 24000/1001 -lavcopts vcodec=huffyuv:format=422p:aspect=1.78 -o outputfile.avi (ie, remove the crop and leave the scale. the other line was my attempt to remove the unneeded lines, but it turns out, its not a big deal, and to just leave them in makes no difference, this is also slightly faster.
