Movies and TV shows purchased or rented from the iTunes Store often carry FairPlay DRM, which restricts playback to authorized Apple apps and devices. DRM-free M4V files play in most modern media players, including VLC.

Often yes, because both extensions use the same MPEG-4 container, so renaming a DRM-free file usually works. Playback can still fail if the file uses AC-3 audio and the target player does not support that codec.
