I inserted a blank DVD at what I'm guessing was exactly the wrong moment, when about to record on it. At first it wouldn't mount. I had to eject it using Terminal. Now whichever blank DVD I insert, it shows up as a burn folder. I presume a small file has been created somewhere that has confused Snow Leopard. How do I fix this, please?
