When setting the iTunMOVI XML tag, cast is set in the 'cast' XML branch. Involved peoples are set in the specified "Function" branch.
iTunes sets for example directors in the "directors" branch, so you have to specify the director as a "Function" 'directors' even when there is only 1 director.
Please try saving an example MP4 file with iTunes to find out other crew "Function" names.
