Thanks for the review.

Sorry if I'm misunderstanding you, but I'm pretty sure the earlier AddMediaStream calls succeed under windows server. I believe the issue is that decoding AVI files isn't supported under windows server (I read something to that effect a few days ago, though for some reason I'm unable to find the link now).

Would adding an extra test (like IAMMultiMediaStream_GetInformation) to see if AVI files can be seeked be alright?

Good point, will fix.
