Files of this type only store video content, so there's no audio, subtitles, or related information. These files are hardly ever seen alone because there's no way for audio to be stored with the video. Instead, they're commonly seen when using a DVD-authoring tool, combined with audio files like WAVs or AIFs, menus, and chapter points, to build a DVD video. Some DVD-authoring programs use an M2A file along with the M2V file, which is a MPEG-1 Layer 2 Audio file. How to Open an M2V File You can open the file with popular media player applications like Windows Media Player, VLC, Winamp, and RealPlayer. However, these programs will only let you watch the video file, not create a DVD from the M2V file. To write the file to a disc in order to use it as a DVD, use software like DVD Flick. This program, and others like it, create standard DVD files, like VOB, IFO, and BUP files, in a VIDEO_TS folder. Freemake Video Converter opens and burns this file format, too, in addition to converting it to several other video formats. Again, though, M2V files are video-only files, so you'd have to add an audio file to Freemake Video Converter, too, and join the two together with its built-in joining option. While these programs aren't free to use, you can also open the file with Roxio Creator, CyberLink PowerDVD, and CyberLink PowerDirector. Most of these applications generate a DVD with the M2V file and an audio file, and quite possibly even subtitle files and anything else that should be part of the DVD. If you find that an application on your PC does try to open the file but it's the wrong application or you'd rather have another installed program open it, you can change which program opens M2V files by default. How to Convert an M2V File Any Video Converter saves this file to all sorts of video formats, like MP4, AVI, FLV, and others. EncodeHD, Oxelon Media Converter, and Clone2Go Free Video Converter also support the M2V format. To make an M2V file, try the free Avidemux software. Still Can't Open the File? If you file won't open at this point, then you're probably misreading the file extension. This is really easy to do because some files share similar file extensions, which can make you think you're opening an M2V file when you're really not. 2MG files, for example, aren't at all related to this file. That extension is used for Apple IIGS Disk Image files. Another is V2M. Although it does share all the same characters, this one is reserved for audio files used by V2 Synthesizer. You could even have a file that uses just one of the same letters, like an M file.
