You have to define the media type for each stream before the multi stream target object is added to any other multimedia object.

The passed media type might only partially describe the media type the stream can accept; this is intended for specifying the major properties of the media type (although you can specify all properties of the media type). This media type might be different from the actually connected media type returned by IltmmMultiStreamTarget::GetConnectedMediaType.
