Created an attachment (id=6761)
 --> (http://bugs.winehq.org/attachment.cgi?id=6761&action=view)
WINEDEBUG="amstream" wine PlayVideo.exe

next I picked the

dlls/amstream/mediastream.c
IMediaStreamImpl_QueryInterface
and added
IsEqualGUID(riid, &IID_IDirectDrawMediaStream)
(maybe this was wrong but should be found, cause it is on windows)

however it crashs at IClassFactory_AddRef
and I have no clue at all, maybe someone could give me a hint
