Don't give up yet. I believe that libavcodec framework is either
missing the framework for handling SARs vs. DARs the way it is described
here (http://www.mir.com/DMG/aspect.html) or I'm personally not
aware of how to use it. The worst case scenario -- Michael will let
us know the part WE didn't know about libavcodec ;-)
Thanks,
Roman.
