[MPlayer-users] Xvid4 and PAR parameters

[Nico]

Hi,
lately I've been plaing with ve_xvid4 and the new par*  parameters, 
which are supposed to indicate the aspect ratio in
the video_es like lavc, but the results are really strange:

par=pal43 yields 0.92

par=ext:par_width=4:par_height=3  => 1.03

par=ext:par_width=7:par_height=5  => 1.32


How is it supposed to work? How to make a simple 4:3 ?

Thanks,
       Nico
