Comments

This user should only pass data obtained from IltmmMediaTypeDisp::GetPortableType to this function. The portable data contains all the information to describe the media type. For example, you do not need to call IltmmMediaTypeDisp::put_Type, etc. You can, if you want to, but you do not have to.

For more information on using the high level method of acquiring the media type, refer to IltmmMediaTypeDisp Interface.
