I am using the burn:/// folder in the Nautilus and want to copy a file to a cdrw and it's giving me this error. Any suggestions?

does this happen even when logged in as root ???

I haven't tried it as root. But i should be able to burn files to a cd under my regular login.

First try it as root, if it works then we are just facing a file-permissions problem. Else we will have to look deeper into the problem

also do ls -l /usr/bin/cdrecord /usr/bin/readcd and post the output

I tried it as root and it still gave the same error. I did the command of ls that you said and here is the output.
ls -l /usr/bin/cdrecord /usr/bin/readcd
-rwxr-xr-x 1 root root 311604 Oct 24 08:46 /usr/bin/cdrecord
-rwxr-xr-x 1 root root 143700 Oct 24 08:46 /usr/bin/readcd

try this:
chmod u+s /usr/bin/cdrecord
chmod u+s /usr/bin/readcd

also do an ls -l on ur cdrom device and post the o/p

I saw a few options around google, maybe you'll get lucky:

1) be sure you have updated cdrecord & kernel versions.
2) kill magicdev
3) kill kscd
4) disabling Autorun-Options; Gnome-Preferences-->CD. (you don't want a CDR mounted if you're going to record to it.) (or just umount before you try to burn.)

I use X-CD-Roast rather than Nautilus' burn:///, so ymmv.

I changed the permissions for the symbolic link thinking that would do something. But then I read the man page for chmod and it doesn't look at the symbolic link permissions. but here is the output of both the /dev/cdrom1 and the /dev/scd0.

ls -l /dev/cdrom1
lrwxrwxrwx 2 root root 9 Apr 9 14:44 /dev/cdrom1 -> /dev/scd0

ls -l /dev/scd0
brwxrwxr-x 1 disk 11, 0 Sep 15 2003 /dev/scd0

I also changed the /dev/scd0 permissions too. Do I have them set wrong?
Also when I try to mount the /dev/cdrom1 I get this error

mount /dev/cdrom1
mount: Not a directory

Was the cdrw inside the computer when you installed Fedora?

Yes,it was already installed.

you can't do this
mount /dev/cdrom1

man mount

I can mount my dvd player using that command. It is located on /dev/cdrom. What do you mean by I can't do that?
