Why is the DVD better than VHS tape?
The DVD is better than VHS tape because it is a digital medium, whereas VHS tape is an analogue medium. This gives it the following advantages: * Superior image quality with higher resolutions. There is more picture data, with no loss from media to screen. * Finer sound quality with more channels and an improved dynamic range. Dolby Digital 5.1 offers six (5 + 1) discrete channels.
