--- Comment #9 from Alexander Dorofeyev alexd4@inbox.lv 2008-05-04 12:25:48 --- First, cleber, how are you generating your logs? They look very hard to read. I've a feeling you are maybe copy pasting from console. There's a better way:
wine ... &>log
What indicates it's amstream related anyway? Is there something in the log to suggest that's necessarily the case.
I see there are numerous pixel format errs in the log as well as some CreateSurface failures. That's serious problems that can lead to crashes, in fact one or few such bugs occured recently due to pixel format overhaul and were fixed. But some issues can be still remaining. They are often hardware dependent, that's why you really should add at least what card vendor you are using with such reports. For example, there's an afaik still unfixed issue with z-buffer formats on Intel cards.
