--- Comment #5 from Maarten Lankhorst m.b.lankhorst@gmail.com 2008-06-28 13:44:37 --- I have submitted a patch that rewrites the avi splitter, if you apply that the avi splitter should work again. Or you can revert the breaking commit for now.
Could you send the enummatchingfilters patch to wine-patches?
