M4V is a kind of video container format developed by Apple. It's similar with MP4 format, but there are still tiny differences in the video and audio codecs. M4V video format is usually used in the Apple movies, TV show episodes and music videos in iTunes store. It's not compatible with many Non-Apple devices, like Android phones and tablets, Windows mobile and other mobile devices, like Xbox 360, PSP etc. To watch the M4V videos on other devices, the only way we can accomplish it is to convert the M4V videos to other common formats, and MP4 is the best choice.
