As for me,
iTunes M4V converter for Mac is the best video converter. Since all iTunes videos are in M4V which DRM protected, making it impossible to be played on Apple unauthorized devices. If you really want to play these videos freely, you may have to get rip of DRM protection at first. After conversion, you will be able to watch these videos on Windows movie player, Android phone, Sony TV, etc. Or you can check more info on
