Also Known As: Digital Video Disc, DVD. Digital Versatile Discs resemble audio CDs in appearance, but have a much higher storage capacity. Hence, they can store rich digital media such as video in addition to audio and computer software. DVD was once called "Digital Video Disc" but the name change reflects its wider uses. As a video medium, DVD offers full length feature films to be stored with exceptional picture quality accompanied by high end digital sound, such as Dolby Digital and DTS. Thanks to the huge capacity of discs, DVD movies are often sold with extra features such as the option to view the movie in widescreen or fullscreen, or the option to listen to the movie or director commentaries.
