I take it back, I still have to sign in as root. When
I first made the changes it opened right up without
requesting the root password, but I tried it today and
gotta give the password. I looked at the permissions
on the cdrecord file and it is owned by root and the
group is users. I also went into setup for xcdroast
but didn't find any type of permission/users stuff. Oh
well, in a week or two I'll try out cdrbq.
