--- Comment #2 from rainy6144@gmail.com 2010-03-07 01:56:41 --- Solfege from Kogado Studio, for one. Without this patch, when a video clip is expected to be played, wine shows a QueryInterface error with IMultiMediaStream's GUID and the game then locks up. With the patch, the video clips are simply skipped with a couple of amstream fixme's and the game continues normally. Since the video clips can be viewed outside the game, skipping them doesn't affect gameplay too much.
By the way, I'm using wine 1.1.35, although the patch is apparently still applicable to the latest git source.
I don't know too much about COM, but since IMultiMediaStream is IAMMultiMediaStream's super-interface, I suppose it should be included in the QueryInterface.
