up to .42 my divx were displayed properly on my widescreen tv, i.e. adapted to 16:9 aspect ratio.
After upgrade to .43 my MD video settings got spoiled, then I relaunched AVWizard and everything went apparentely fine.
In the mean time I realized that proper video driver (unichrome) were missing, so I installed them and from that point on my divx are no more scaled to 16:9.
I guess that video driver installation changed a bit my xorg.conf, loosing some specific settings.
As I'm not that familiar with those settings, is there anyone that can give me a hint on how to settle this?
