Apple DVD Studio Pro 4 - Manual (Page 38)

Important: When displaying estimated sizes, DVD Studio Pro uses the “1000 bytes equals
a kilobyte” system. This means that the estimated sizes refer to the amount of space they
will require on the DVD and will be a bit larger than the file sizes shown in the Finder.
While the Finder shows binary-based file sizes, you can use its File > Get Info command
to see both the binary-based file size and, in parentheses, the “1000 bytes equals a kilobyte”
size.
Disc Options
You have a variety of DVD discs to choose from. The one you choose depends on your
content, your budget, and whether you intend to use a DVD replication facility. DVD sizes
are typically referred to with names such as DVD-5 and DVD-9. While the number in the
name is intended to provide general guidance as to the capacity of the disc, it should
not be relied on too strictly. (Note that a DVD-4 disc has a higher capacity than a DVD-5
disc.) The following tables list the common sizes used.
