Very Computer

I'm running several cd-rw programs and all seem not
to want to work when running as non-root.  The cdrom
and cd-rw drives are set up as:

lrwxrwxrwx   1 root     root            3 Aug 31 21:29 cdrom -> sr8

brwsrwsrwx   1 root     root      11,   8 Aug 29 18:58 sr8

for the cdrom and

brwxrwxrwx   1 root     root      11,   0 Aug 29 18:58 sr0

for the cd-rw

when I run cdrtoaster and try to blank a cd-rw media it says:

cdrecord: Operation not permitted. Cannot do mlockall(2).

When I try and run ripperX as non-root it says:

Error Code 14:
Cdparanoia complains /dev/cdrom exists but isn't accessible.

and I've made sure there is a cd in the cdrom drive.

When I try and run kisocd and click on options, it lists the incorrect
cd-rw drive and says below it:
I have to be root to scan the scsi-devices!

All of these programs run fine as root, so it must be some
permission problem.Any help would be greatly appreciated.
Thanks,
