What if the disk I just burned is giving me an error?
• Burn at 1X, 2X or 4X. The slower the burn, the less room for errors, it takes time to do things right.
• Use DVD-R media, not DVD+R media. For many years by default, Apple's DVD drives were DVD-R only. Apple's default drive hardware has only moved to DVD+R within the past year or so. If you have an older Mac, you need to swap out your internal drive or get an external DVD+/-R(W) drive to view or record DVD+R.
• Use quality DC/DVD media. There are many variations in media and it really can make a difference. If you're considering a new optical drive, NEC and Pioneer are highly recommended brands by many Mac users.
