No need to scale with xvid any more!

[evade]

The pixel aspect ratio function of xvid works properly with mplayer and xbox media center!

this command yields a perfect movie without scaling which will play back with the correct aspect ratio (ntsc 16:9):

I think there are presets like par=ntsc169 which is the same as par=ext:par_width=237:par_height=200 or par=pal43 which is the same as par=ext:par_width=213:par_height=200

Unlike lavc the par options would be the same no matter what cropping you do to the movie.

in -dev-eng archive there's a patch to encode using :aspect=x/y option.
aspect specifies the DAR, so it's easier to use.
Now if only standalones supported this feature ...
