I suppose this is a permissions problem?

Nevermind. . . i'll accept defeat and do it as root. Didn't 5.8 let the user burn CDs straight out of the box? ( as far as cdrecord? )

By the way, this is my 100th post! Do i get a blue star or something? A 1337 hax0r medal?

For future reference: if you have k3b installed (it comes with 5.9 standard), you can use k3bsetup to set the permissions. It sets them to 4711. If you want to change the permissions from commandline you can do it like this:
Code:
chmod 4711 /usr/bin/cdrecord

Actually, i did take a look at the k3b set-up, because i remember that xcdroast had to be set up also, but i couldn't figure it out and i was in a hurry.

I did want to use chmod but i was afraid to break something. For instance, i didn't know about the SUID part that you just showed me. I learned something new today. Thanks.
