I have a G4 Powerbook. I am searching everywhere to find out how to: 1. Take a song from ITune and put into Garage Band or another program so that I can slow the speed or tempo of the song without changing the pitch. 2. Also, how do I copy a DVD into my G4? Is "Crunch" the appropriate program or is there another way of accomplishing this task? Thank you in advance for your sound replies.
