Digital Encoding 
Audio and Video Preparation/Encoding 
DVD's increased complexity means additional processes have to be carried out compared to CD. For DVD Video, (and audio-visual segments of DVD-ROM) the digital video and audio is compresses using a technique called MPEG2 encoding. This reduces the quantity of video and audio information to put on the disc without reducing quality. DVD also allows inclusion of different versions of the movie soundtrack with different laguage dialogue.
