DVD Capacity Not actualy 4.7 GB..?

A word of caution about DVD capacity — when marketing people talk about
the 4.7GB capacity of a DVD, they mean 4,700,000,000 bytes. However, for
technology purists, that number translates to about 4,482MB or only 4.377GB
because 1,024 bytes are in each KB and 1,024 x 1,024 = 1,048,576 bytes in a
MB, and so on. The bottom line is that you can only fit about 4,482MB of data
onto a DVD.
