I want to buy an external DVD burner to attach to my new iMac. Any suggestions for the best, most reliable one? After reading about numerous problems people are having with the internal one and experiencing a failure after only 15 minutes of play, I don't want to mess with the internal one. It said my DVD was either dirty or scratched. It is as pristeen as when I burned it and doesn't have so much as a fingerprint on it. It plays in all my other DVD players just fine. I figured the player would be a problem considering CD's and DVD's come out just as hot as if they had been in a toaster I don't mind buying a new external burner and I don't want to take my iMac back because I am happy with the 24" monitor, it looks great. So what are your suggestions for the best one?
