I'm constantly amazed by the number of people on this forum who say they have new machines and repeatable problems and who sit around and moan waiting for an Apple update to fix it. Have you not heard of the Apple store and the genius bar? If your dvd really crashes 'every other time', take it to the x*??!! Apple store and get it fixed! Why is that so difficult?? It is most likely a faulty drive - but instead of going and doing something about it, you sit around forever waiting and complaining for a software fix that'll never come.
Just to get things clear - if you have a new MB or indeed any other new Mac less than a year old, IT IS IN WARRANTY. If there is a reproduceable fault take it in to the Apple store and show them. If it don't work - they are obliged to fix it.
Well I guess it's too bad for those of us who live in Alaska where there's no Apple store! Oh, I think I'll cartwheel on over to the Genius Bar. I hope there's one in Seattle! Excuse me for complaining. Stick that in your juicebox and suck it!
