Can you convert iTunes DRM-protected M4V videos to MP4?

As mentioned above, Apple developed the M4V format. This format is almost exclusively used for movies, music videos and TV shows downloaded from the iTunes Store and can be opened by iTunes and QuickTime Player.

Files in this format are potentially protected by FairPlay, which is Apple's digital rights management (DRM) technology. A DRM-protected M4V file is encrypted. Only authorized iTunes and Apple products can have access to it. Before converting DRM-protected M4V videos, you need to remove DRM first. The good news is the removal can be done easily with DRM removal software such as Requiem. It's okay to remove DRM and convert M4V to MP4 as long as the converted files are for personal use only. So, the answer is yes.
