DVDs are commonly used as a medium for digital representation of movies and other multimedia presentations that combine sound with graphics.
The DVD specification supports disks with capacities of from 4.7GB to 17GB and access rates of 600KBps to 1.3 MBps. One of the best features of DVD drives is that they are backward-compatible with CD-ROMs, meaning they can play old CD-ROMs, CD-I disks, and video CDs, as well as new DVD-ROMs. Newer DVD players can also read CD-R disks.
DVD uses MPEG-2 to compress videodata.
