cd writing problems - solution found!

[Jeff Vian]

As others have said my cdrom mounts read only.

When using the cd burner /dev/cdrom is NOT mounted, and the raw device 
works just fine.

Your fix probably leaves room for problems at some point, since NO 
cdroms are writeable. (cd-rw disks are different)
