What is DVR MS File and How to Convert to MP4

Have you ever needed to convert a video from your old Windows Media Center DVR recordings? If so, you've likely encountered the DVR MS file format. DVR MS files are a proprietary video format created by Microsoft to store TV recordings made on Windows Media Center set-top boxes and software.

While useful for Windows Media Center, DVR MS files can be frustrating if you want to watch your recordings on other devices. Most media players and smart TVs do not support playback of the DVR MS format. Fortunately, it is possible to convert these recordings to a more compatible MP4 video format.

In this easy-to-follow guide, you'll learn what DVR MS files are and how to convert them to MP4 using free software tools.

Part 1. What is DVR MS File?

DVR MS, or Digital Video Recording - Microsoft file, is a proprietary video format developed by Microsoft in the early 2000s for use with Windows XP Media Center Edition. Introduced in 2002, Windows Media Center made it simple for Windows users to watch, pause, rewind and record live television on their computers.

A key component that enabled rich digital video recording features was support for the new DVR MS file format. The DVR MS format allowed entire television streams to be encoded and stored efficiently on computer hard drives. It was designed specifically for capturing TV video, supporting features like program guide data and channel details metadata.

Some key attributes of DVR MS files include:

Developed for efficient video storage and smooth playback in Windows Media Center
Can be generated in different resolutions like standard definition 480p or high definition 1080i
Typically uses Windows Media Video (WMV) video compression for reduced file sizes
Contains metadata like program name, description, channel call signs
Integrates well with Media Center for scheduling recordings, viewing libraries

In its heyday, Windows Media Center with DVR MS file recording capabilities was praised for ushering in mainstream digital video recording and TV viewing on Windows PCs. However, as the app faded in popularity and support ended, it can be tricky for longtime Windows Media Center users to access their collection of stored DVR MS recordings and home videos. Converting the files to more compatible formats can help breathe new life into those dusty digital archives.
