File Extension M4V
File extension M4V is used to indicate MPEG-4 Video files. The file extension is used especially for videos that users download from the iTunes Store which belongs to Apple. The videos include television episodes, full- length movies and music videos. It is similar to MP4 files but could be copy-protected by use of FairPlay DRM protection for copyright.

If a user wants to play an M4V file extension that is protected they must use an authorized computer. The user can authorize their computer by use of iTunes and the account that they used to buy the video. As for the M4V files that are not protected, they can be recognized then played using any other video players.
