About burning CDs and DVDs
You can use iTunes to create your own discs containing audio and video from your iTunes library.

To make your own CD or DVD, you need:

A computer that can burn discs. To create an audio, MP3, or backup CD using iTunes, your Mac must have an Apple Combo drive or SuperDrive. To back up your library to DVD, your Mac must have an Apple SuperDrive. Some third-party DVD burners may also work.
An iTunes playlist containing the music and video you want on the disc.
A blank disc. If you plan to play the CD on a consumer CD player (not only on a computer), you need to use a blank CD-R disc, not a CD-RW disc. You can use DVDs with your computer, but most DVD players can't read data DVD discs. ("RW" stands for "read-write" and means the disc can be erased and reused.)
The number of songs a disc can hold depends on how the songs were created on your Mac. You can fit about 74 minutes of music (about 20 songs or 150 MP3 files) on a 650 MB CD. Some CDs can contain 80 minutes (700 MB) of music. A DVD can hold 4.7 gigabytes (GB), almost five times as many songs as a CD.

Some non-Apple CD-RW and DVD-RW drives may also work. To find out if an external drive is compatible, choose iTunes > Preferences, click Advanced, and click Burning. If the drive is listed, it's compatible.

Movies purchased from the iTunes Store can't be burned to a DVD or VCD that will play in a DVD player or Video CD.
