About formats

WTV (Windows Recorded TV Show) is a digital video recording format developed by Microsoft and introduced in July 2008 with the Windows Media Center TV Pack for Windows Vista. The format was designed to replace the earlier DVR-MS recording format used by Windows Media Center, offering a more capable container for recording live television broadcasts. WTV files store video in MPEG-2 or H.264 encoding alongside multiple audio tracks in AC-3 or MPEG audio format, along with closed caption data, electronic program guide metadata, and copy protection flags. The container uses an internal directory structure that supports time-shifting features, allowing Windows Media Center to record content while simultaneously enabling playback from the beginning of the recording. A rich metadata framework preserves detailed program information from the electronic program guide (EPG), including show title, episode description, genre, ratings, and original air date, making it easy to organize and browse recorded content. The format supports both standard definition and high definition recordings from digital cable, over-the-air ATSC, and ClearQAM tuner sources. WTV files are natively accessible through Windows Media Center and can be converted to the simpler DVR-MS format using built-in Windows tools. While Windows Media Center was discontinued after Windows 7 (with limited support in Windows 8), WTV files remain in personal media archives and can be processed by third-party video tools.

DVMS (Dutch Voice Messaging System) is a telephony-grade audio encoding born from the Netherlands' early push toward digital voicemail infrastructure. Deployed through KPN (formerly PTT Telecom) in the mid-1980s, the format stores mono voice data at a narrow 8 kHz sample rate, prioritizing compact message size over sonic breadth. Audio is compressed with a proprietary variant of logarithmic companding similar to European A-law encoding, squeezing recordings to roughly 8 kbit/s while keeping speech intelligible. Each file carries a small header identifying sample rate, compression type, and message metadata, which made automated routing across early PBX and voicemail systems straightforward. Although DVMS never gained traction outside Dutch telecom circles, it influenced how European carriers designed later voice messaging protocols. Tools like SoX and several legacy telephony libraries still read and write DVMS files, allowing archival playback of decades-old messages. Among its practical advantages: extremely small file sizes (a one-minute message occupies roughly 60 KB), reliable speech clarity despite aggressive compression, and a simple container layout that is easy to parse programmatically.

Frequently Asked Questions

What is the benefit of converting WTV to DVMS?

Extracting audio from a WTV recording into DVMS lets you save the soundtrack of a TV show for offline listening on any device.

What program opens DVMS files?

Voice messaging systems and telephony applications can play DVMS audio messages.

Will the audio quality match the original?

You can set the output bitrate to match or exceed the original audio quality. Higher settings preserve more detail from the WTV source.

How fast is the audio extraction?

Audio extraction is quicker than full video conversion since only the sound track is processed. Most files are done within seconds.

Can I choose the audio bitrate?

Yes. Adjust the bitrate, sample rate, and channel count before converting to get the DVMS quality that suits your listening needs.

Is registration necessary?

No. Basic conversions work without an account. Signing up is optional and provides access to extended features and larger uploads.
