I'm *really* a novice at this, but the first time I tried to record a
DVD (I use cdrecord) I learned that the media needed to be formatted
first. I don't know if what your using is already formatted, if your
software does it for you or if it's even needed.

Using the cdrecord software, there are flags that will let me know.
