**Can't burn cds, of my playlist??**

I can't burn a playlist, down on a cd??
All it does is try to do it, and everyting seems normal, but then it gives me this "fail message":(i have it in danish, so im going to try to translate it) "The try on burning the disk failed. The burning failed because of a writingfail in the media", and then there's noting on the CD?

I really hope someone can help me!
