As an mp4 user (and not an mp3 user), mapping "Publisher" to "Studio" doesn't work for me. For commercial movies, "STUDIO" refers to the organization that puts the movie "in the can" - that is, creates the movie. "PUBLISHER" is a.k.a. "distribution company" or "releasing company" is the entity that is responsible getting the movie in front of the people who pay (one way or another) to see it. These days many studios do their own distribution, but historically production and distribution were performed by separate legal entities, and especially for films destined for release internationally, multiple PUBLISHERs distribute the same movie. Today, there are sometimes multiple distribution channels in the same country - e.g., theaters vs Netflix vs DVD/blu-ray, etc. So: is there any way to stop "Create iTunMOVI.mta" from automatically copying "ID3v2 PUBLISHER" to "ID3v2 STUDIO"?
Alternatively, do you know of a tag that I can use for the movie distributor? Is there a tag named Distributor?
