I have made a very little patch to modify the behaviour
when you use a ratio in the resize properties page :
before the patch, ffdshow always apply this formule
(aspect ratio = a1/a2) : y=a2*x/a1;x=x
it's good when you use a video with video ar>screen ar
(an example (screen 16/10) : 576*240 => 576*360)
because it's an upsize
but whith a video with video ar<screen ar (4/3 video)
ffdshow does that : 720*576 => 720*450, I think it's
not good because it's a downsize => lose of video
information
I thing the good resize is : 720*576 => 924*576 (upsize)

My patch modifies ffdshow to do an upsize in all the
situtations.
