As we know, there are 2 kinds of iTunes movies: Protected and Unprotected (Videos, movie, TV shows, etc. purchase from iTunes Store are usually protected M4V files). For unprotected iTunes videos, it's easily to burn them onto DVD discs with regular DVD burners. However, for protected iTunes M4V movies, you can't burn them to DVD unless you remove the DRM protection first.

Note: Aimersoft Video Converter Ultimate for Windows can help you burn both protected and unprotected iTunes video to DVD while the Mac version can only create DVDs from unprotected iTunes files.
