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.

Adaptive Multi-Rate (AMR) is a compressed audio file that is often used for speech coding. The AMR speech codec focuses on narrowband signals, which makes it ideal for voice recordings and radio. It is used regularly in Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS).

 

How to open an AMR file?

Since AMR files are often used on mobile phones, including for MMS messaging, most 3G mobile devices are able to open them. AMR also opens with VLC media player, QuickTime, RealPlayer, and Xine.

 

Other software, such as the free audio-editing software Audacity, can open AMR files. Download audacity easily at SourceForge.net. Because AMR files are heavily compressed and focused on narrowband signals, they are not suitable for music files.
