heres a mpeg with aspect
http://samples.mplayerhq.hu/MPEG-VOB/mpeg2-ES/detect.m2v
480:480 video with aspect of 4:3 (640:480)

then add
a switch_ratio -1
to input.conf


VO: [directx] 480x480 => 640x480 Planar YV12
V:   1.1  34/ 34 11% 15%  0.0% 0 0 69%

press a 

Movie-Aspect is 1.00:1 - prescaling to correct movie aspect.
VO: [directx] 480x480 => 480x480 Planar YV12

i think ingo might have wanted switch_ratio -1 to go back to the
original aspect ?

was -1 ever supposed to work? -1 is not listed in the docs
from DOCS/tech/slave.txt:

switch_ratio [value]
    Change aspect ratio at runtime. [value] is the new aspect ratio
expressed as a float (e.g. 1.77778 for 16/9).
    There might be problems with some video filters.

switch_ratio might have to go into the properties section at the end of
slave.txt if it supports those get_property things.
