Trouble burning CD's

I'm having trouble burning CD's. First I tried gToaster, then I tried with the command line using cdrecord, but neither worked. Basically, I click 'record' from gToaster but it doesn't do anyting. I really don't know what to try, I did 'cdrecord -scanbus' from the shell and this was my o/p:

[root@localhost javi]# cdrecord -scanbus

I tried gtoaster once and could never get it to work. I've had the best luck using k3b. It just works and configures better than xcdroast, eroaster, and gtoaster.

Can you do stuff from the command line successfully?

I finally tried doing it in the shell and it tells me:

Error trying to open /dev/scd0 exclusively ... retrying in 1 second.

bailing out

Not sure what this means.

Also, I had to do this as root. If I want to record as any user, can i just change the permissions/group for that file?
