Hello, I have a new macbook, and sometimes when I insert a cd, it's ejected automatically (Preferences are set right), and sometimes when I get the option to choose the application (ex. finder), and I double click in the cd, it appears the symbol for burning, I must did something wrong before when I tried to burn another cd, and now I click burning and always appear the messagge: Burning the disc failed because communication to the disc drive failed. Error code 0x80020022. I would appreciate very much if someone can help me. Thanks.
