If I open the m4a audio file with Amadeus Pro and add or amend the metadata then save the file when I open it up again with QuickTime and open the Movie Inspector <0021> now appears under the rows metadata. This does not happen if I amend the metadata with the other audio file editor I was using before switching to amadeus Pro.
I have concluded the <0021> footprint has probably been left by Amadeus Pro. Does anyone know if it is possible to stop the annoying <0021> being added?
