Comments

This method allows you to reset the whole media type (format buffer, type, subtype, etc). All the values set through any IltmmMediaTypeDisp::put_xxx properties are reset to defaults.

You would typically call this method if you want to start building the media type all over without freeing the existing interface and recreating a new one.

This method is implicitly called when you create a new instance of the IltmmMediaTypeDisp interface.
