Is a multimedia container for playing audio and video in karaoke mode. There are several options for playback, which switch off all of the streams. This format is supported by a few PC players, but is widely used for DVD-players and home theater systems.
The *.m2v files are normally destined to be multiplexed (muxed), which is the process of adding audio data and perhaps other streams such as subtitles, before use. M2Vs are created by demultiplexing (demuxing) an existing MPEG-2, or by converting another video format to MPEG-2. The file extension m2v is mostly found with SFV Host Files.
