Music or QuickTime movies from CD-ROM discs played from your PowerBook computer may sometimes sound choppy. If playback of QuickTime movies and Audio CDs are choppy, slow, skip, or jump around, check the following:

Step 1

If you have a PowerBook, turn off Processor Cycling (in the PowerBook Control Panel).

Step 2

On all Macintosh and PowerBook computers, turn off Virtual Memory (in the Memory Control Panel).

Step 3

Turn off or quit applications running in the background before you try to play the music or the movie.
