Microsoft Digital Video Recording (DVR-MS) is the multimedia container file format that results when a Stream Buffer Engine (SBE) records television (TV) content. DVR-MS is proprietary to Microsoft, which designed it to store TV recordings captured by Microsoft products. In 2008 (with Windows 7), the Windows Recorded TV Show (WTV) format replaced DVR-MS.

 

How to open a DVR-MS file?

Microsoft Windows 7, 8, and 10 still support DVR-MS files. Therefore, a DVR-MS file opens with Windows Media Player. If an application requires DVR-MS, then Microsoft recommends using the following utility to convert WTV to DVR-MS: \Windows\ehome\WTVConverter.exe.

 

Other players that can open a DVR-MS file include VLC media player, Cyberlink PowerDirector, Cyberlink PowerDVD, and Cyberlink PowerProducer.

MPEG 4 Audio (M4A) compresses and encodes audio files by using one of two coder-decoder algorithms: Advanced Audio Coding (AAC) or Apple Lossless Audio Codec (ALAC). M4A files are smaller in size while simultaneously better in quality than MP3 files, with which it shares the most similarities, in comparison to all other audio file formats.

 

How to open an M4A file?

M4A files open in most well-known, audio-playback programs, including iTunes, QuickTime, and Windows Media Player. For Apple users, iTunes is the default program to open M4A files. For Windows users, the default program is Windows Media Player. Users can also preview M4A files by highlighting the file and pressing the spacebar.

 

Additionally, M4A opens in VLC media player, Adobe Premiere Pro, Elmedia Player, Winamp, and a host of other programs.
