CD burning problems

[Paul Higgins]

Does anyone have experience with either K3b or X-CD-Roast?  Both of these are 
misbehaving when I try to erase a CD-RW in my iBook.  The erase fails, and 
K3b says something about how cdrecord is not running with root privileges and 
recommends running some setup thing that I can't find in any of the menus.  
The online help isn't particularly useful when it comes to this either.
