Yet other acronyms...

there is a need to update mapping from format specific to MediaInfo names (MediaInfo Names).
But it won't work out of the box due to that (need to add ALAC there, or something about MOV).

Please a sample file.
Would be nice if you do the mapping from Apple names to MediaInfo names, I may manage the other issues if I have a sample file.
