Currently Copy Protection is listed under CD as its own media type. I have the Enhanced CD by A-Ha which is copy protected. The data track has the decoding player in it.  This medium should be listed as Copy Protected Enhanced CD but that isn't a choice. Maybe make Copy Protection a medium flag instead of a type so Copy Protection can be added to any medium in the future and avoid proliferation of medium types?

Failing to do that, please check the current catalog of media types, annotation fields and disambiguation fields to see how many different combinations there are and add those combinations ('Enhanced Copy Protected CD', for example) to the list of media types.
