I bought some DVD-R's today and tried to put some vids on one, but its says disc not recognised. I went into the settings and only the boxes for CD-R's and CD-RW's are checked. It won't let me check the box to use a DVD-R.

Question, is this because my PC isn't good enough for the disc (the disc actually has more memory than my hard drive!) or do I need some kind of update?
