I reviewed the drives specs, and it does burn CD-R's and CD-RW's in
addition to DVD's. I will do another post asking if anyone else has
gotten this burner to work with FreeBSD.
Do you know if there is a way to bet a more verbose message (why the
operation is not permitted) or to debug this problem (I am confortable
working with C/C++ but have never looked any FreeBSD source)?
