I have the MBP, and I'm trying to burn a music CD. I have my MP3's on my computer, and I have dragged and burned them onto an empty CD. They will play if the CD is inserted into a PC or back into my MBP but my problem is that my CD player both in my vehicle and my portable CD player are giving me errors. They will not play anything burned by my MBP. Is there a different format or something I should be doing instead to make them work? Is there something wrong with my burner? Could it be the CD's I'm using? Although they worked fine with my powerbook. Any help or suggestions would be great.
