Setting ITUNESMEDIATYPE

Support
#1

How do I set ITUNESMEDIATYPE to iTunesU? Whenever I attempt to set the field to iTunesU, the field is reset to "Unknown".

#2

It's currently not possible but will be with the next version of Mp3tag.

#3

This is now possible for MP4 files with the current Development Build using iTunesU as media type.
