WTV is a video file that is recorded by Windows Media Center. This program plays multimedia content, records TV shows, and encodes video using specific compression tools like MPEG-1 Layer 11, MPEG-2, or Dolby Digital AC-3. The WTV file may also include digital rights management, as well as descriptive metadata. When a TV show is recorded by Windows Media Center, the Stream Buffer Engine creates the WTV files, and the default saves them in the users/public/recorded TV directory. The shows can be opened and played in Windows Media Center. The WTV format replaced the DVR-MS format that was in the Windows 7 version of Windows Media Center. Users have the option to convert back to the previous Windows 7 version by right clicking them on Windows Media Center.
