M4V

The M4V file format is a video container format developed by Apple and is very similar to the MP4 format. The primary difference is that M4V files may optionally be protected by DRM copy protection. Apple uses M4V to encode video files in its iTunes Store. Unauthorized reproduction of M4V files may be prevented using Apple's FairPlay copy protection. A FairPlay-protected M4V file can only be played on a computer authorized (using iTunes) with the account that was used to purchase the video. [1] In QuickTime, M4V videos using FairPlay DRM are identified as "AVC0 Media".

MPG

MPG (also referred to as MPEG) is the acronym for the Moving Picture Experts Group. Files with the .mpg extension often contain movies that are distributed over the Internet. The .mpg format is also given to many of the VCR videos that are converted to downloadable movies. For example, if you had a VCR containing one of your favorite movies from the 80s, you could convert it to a downloadable movie in the .mpg file format.
