Window is messed up or missing when opening some avi files

[kettyo]

Hello everybody,

I have a problem when i open some divx avi files the video window is missing from the screen or showing garbage.
When i select original aspect ration from the menu the screen comes up correctly.
But when i open these files again the video window is messed up again so i always have to choose original aspect from the menu though i always use it never use custom aspects.

What could be the problem? How can i solve it?

With WMP it works but BSPlayer is so much better i wouldn't like to downgrade.

Thank You!

Ps: using latest version
