Since one or two month, my Macbook Pro was systematically ejecting all blank DVD-R that I was inserting. I was afraid that it was broken. Fortunately, before trying to kill my Mac, I just made some search on the Internet and I found the solution. Simply use an air can and give some “fresh” air to the drive. So did I, and it work just fine now :-) Tip found at http://discussions.apple.com/thread.jspa?threadID=1684759&tstart=0
