DVD-Audio

DVD-Audio offers an excellent sound quality: six-channel uncompressed sound at a resolution up to 192kHz (compared with a CD's 44.1 or Dolby Digital's 48). Although much of a DVD-Audio disc is taken up with the sound, the specification also allows for visual material - for instance, text, accompanying slideshows and a limited amount of video. Virtually all DVD-Audio discs can play on DVD-Video players, albeit with inferior Dolby Digital or DTS sound.
