Picture is upside down when playing DivX movies
We've had a few reports about this problem and the majority of the people with the problem are running Windows XP. The easist solution seems to be to goto the Tools->Options->Performance->Advanced menu and simply deselect the "Use video mixing renderer" option. While this option works for many it doesn't solve the problem for everyone.
You can find more possible solutions by reading the upside down problem thread in our forums.
