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.
