Media Converter for Mac free is the best video converter for me to convert iTunes M4V videos to MP4 format. We know all iTunes videos are encrypted with fairplay DRM protection, it can be played on Apple devices only. If you are eager to enjoy all iTunes videos on Android phone, Windows media player, Samsung smart TV, etc. You may need to use a DRM removal tool to crack DRM protection and convert videos from M4V to MP4 with zero loss quality at 30x faster speed. After conversion, you will be able to watch all iTunes movies on any devices freely.
