免費線上 WTV 轉 OGG 轉換器

WTV is a format for videos recorded by Windows Media Center where video is encoded by MPEG-2, MPEG-4 or h.264 and audio - by MPEG-1 Layer II or Dolby Digital AC-3. WTV file can contain video, audio, text and other data. The container replaced DVR-MS that was used by previous versions of the Windows program. WTV supports DRM that allows protection of the content by its owner.

This format is free, which apparently is one of the reasons for its popularity. The used codecs supports variable bit rates (as a default), and .ogg files usually play back easily on all platforms. All things being equal, the sound quality exceeds that of mp3 somewhat.
