CD permissions

[JB]

I changed my fstab setting from owner to users and ro
to rw but I still have to log into root to use the CD
burner. I am currently on a windows box and when I try
to download that cdrbq I get a 15k download. I am
using  xcdroast which seems to work fine except that I
have to log in as root to use it. I found this bit of
information in the HOWTO's about this subject.

How can this be set up so that a user can burn CDs
instead of always being root?
You can add the setuid-bit to the cdrecord-executable.
However, this might be a security risk. Just setting
the permissions on the device files does not help as
cdrecord issues privileged commands via the SCSI
generic interfaces.
which cdrecord
chown root.root /usr/bin/cdrecord
chmod 4111 /usr/bin/cdrecord

I wonder if I should change my fstab back or if this
chown, chmod is the next step?
