Overview
Unless you've been living under a rock for the past couple of years, you've probably heard of DVD video and what it can do. This disc-based medium delivers video quality twice as good as conventional VHS tape and unlike VHS tapes, the discs will never wear out with repeated viewing. What's more, the format allows for different versions of a film or additional material because a DVD can store data on both sides of the disc and on multiple "layers".
When it comes to audio, DVD is a winner as well. DVD can deliver two channels of standard CD-quality sound and several configurations of Dolby Digital, from mono sound to 5.1-channel surround. Most DVDs offer multiple language and subtitle options and a host of other features, including alternate sound tracks that can be used for an isolated music score or a forum for the director, the writer, the stars, or a noted film critic to engage in running commentary on the on-screen action.

Different Menu
