Don’t all Blu-Rays still come with a digital code to download the film?

I’ve never used that as I have used iTunes for years. Very conveniently get all my movies automatically downloaded onto my hard drive.

It doesn’t work outside QuickTime or iTunes. They are m4v “protected” files, not just mp4.

It only works in iTunes or QuickTime player. This is to protect it against you copying or altering it etc.
