M2TS

The .m2ts file extension is used to store BDAV MPEG-2 files that can be streamed from Blu-Ray discs in order to provide "picture-in-picture" DVD effects. "Picture-in-Picture" affects allow a user to view to separate video files on a single screen.The M2TS files are actually container files that store other media data. The files can be burned to Blu-ray discs for viewing on Blu-ray players and can also be played in the PS3 gaming system that is distributed by Sony.

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.
