Dont know if you've got your answer but here goes...

Film Tie-In and MTI (Movie Tie In) are the same thing. It means that the front cover has the movie poster and maybe there will be a blurb about the movie in one of the first few pages. The story itself remains unchanged.

BOX POC is Pocket-sized Box Set. Which is a box set of a book but the books are quite a lot smaller in size to fit in your pocket. Depending on the publisher the book may or may not have been abridged (i.e. some content cut out). You will need to do the research here.

A-format is the size of paper used in printing. It's a common term in UK and Australia. A-format usually means mass market paperback sizes. Content usually not affected.
