I don't use the GUI wrappers for burning CDs or DVDs, as burning seems problematic enough that the wrappers cannot be trustworthy. I use the growisofs command line for DVDs, and the cdrecord command line for CDs. I save the commands I've used in a file with some comments, so I can use them again later. ____________________________________________________________________ TonyN.:' <mailto:tonynelson@xxxxxxxxxxxxxxxxx> ' <http://www.georgeanelson.com/>
