Hix, I just burn a DVD-R two days ago but to day is the worst day ever with my macbook. I inserted a blank DVD and Macbook ejected it after some seconds. I tried many times with some several brand DVD but it is still not working. I already search round and found out many people have the same problem but I still dont see any good solution. Someone suggests that I should call Apple but I am in Vietnam and there is not any Apple Care here (OMG, I bought this Macbook in Japan 😎 ). Some tells the firmware causes the problem but dont see anything help to solve. T.T Help me! It doesnt work with blank CD too. Superdrive now is just like a DVD-drive 🙁
