[MPlayer-users] Playing 3d O/U files

Hello all.

I'm having some troubles playing 3D mkv files.

The test file I'm using is Big Buck Bunny Sunflower edition, 1920x1080

File format is Over/under, so it's actually a 1920x2160:
$ mplayer bbb_sunflower_1080p_60fps_stereo_abl.mp4

Movie-Aspect is 0.89:1 - prescaling to correct movie aspect.
VO: [vdpau] 1920x2160 => 1920x2160 Planar YV12  [fs]

The problem is that it gets scaled (automatically?) so that outputted
image is centered and half width, leaving two ugly black borders (and
bad aspect ratio... the bunny seems slim! :) ).

I've run many tests with -vf scale=x:y trying to output a vertically
compressed image, but in vain. :(

Any hints?
