I want to transfer my music collection to my mp3 player and am looking for the fastest way do remove copyright protection, does doing it in mp3/data cd/dvd remove copyright protection so I can put it on my mp3 player or do I have to use cd audio only? also does anyone know what the message 'unknown error occurred(4450)' mean when burning cd audio with iTunes and if there is an unsuccessful burn attempt does it still count towards my 7 burns per track count
