Three times in the last two months I’ve had to deal with stuck DVDs in the MacBooks and MacBook Pro in the house. Unfortunately, all of the 
laptops/notebooks’ are slot-drives that do not have the pinhole that allows you to manually eject the stuck DVD/CD. Why, oh why is there no pinhole? I tried a number of things that I thought I would never do to a DVD drive. Eventually I had to go to Google for my answer(s). Macosxhints had some really interesting (dangerous?) suggestions.
