About DVDs

The Digital Versatile Disc is quite a wonder:

it’s physically small, like a CD, but packs

nearly seven times the data into the same

space: a CD stores roughly 700 MB, while a

DVD holds approximately 4.7 GB. In addition

to storing all this data, DVDs can be set up

so they automatically play movie ﬁles and

include a menu system to give you control

over how the content plays.

DVD physical formats

Before you rush out and buy a mega-pack of

blank DVDs, take a few minutes to acquaint

yourself with the different formats that are

out there.

u

DVD-R. DVD-Recordable discs can be

burned once, and then played back in

nearly any consumer DVD player and

DVD-capable computer. When pur-

chasing DVD-R media, be sure to get

DVD-R (General); the other type, DVD-R

(Authoring), is used in professional DVD

writers and is not supported by iDVD.

The discs Apple sells are DVD-R format.

u

DVD-RW. DVD-Rewritable discs can

be erased and burned hundreds of times,

which make them great for testing

purposes (you can burn iterations of your

project onto one DVD-RW disc, instead

of making lots of DVD-R coasters).

u

DVD+R, DVD+RW. These two formats

use a different method of recording data

than DVD-R and DVD-RW. They don’t

offer more storage or features, and cost

about the same as the -R and -RW discs.

u

DVD-ROM. DVD-Read-Only-Media

discs cannot be burned because their

data has already been written to disc. The

iLife installation disc is an example of

DVD-ROM.

4x DVD Media Alert!

Before you burn any DVD disc, make

sure your SuperDrive’s ﬁrmware has been

updated. All SuperDrives can burn 1x-

and 2x-speed DVD-R media. When using

4x-speed media, however, some older

mechanisms can not only fail to write

the disc, but they can also be perma-

nently damaged! Fixes are available—see

for more information.

DVD Logical Structure

A blank DVD contains no information or

directory structure. The way a DVD’s data

is stored on the disc depends on how the

disc will be used.

u

DVD-Video. A DVD that contains

just a movie (and its associated menus

and extras) is in DVD-Video format.

The folders and ﬁlenames are speciﬁc:

a folder called VIDEO_TS stores all

of the movie’s video and audio ﬁles.

iDVD typically creates DVD-Video

discs.

u

DVD-ROM. When you store just data

on the disc, without the need to play

back automatically in DVD players,

the disc is in DVD-ROM format. This

is just like using a CD-ROM, only with

more storage capacity. The Finder can

create DVD-ROM discs when you’re

backing up data, for example.

u

Hybrid DVD. You can store a DVD-

Video project on a disc that also con-

tains DVD-ROM data, which makes

the disc a Hybrid DVD. iDVD can

create Hybrid DVDs.
