All,
I was getting exactly this same error following a fresh 8.1 load

the solution was explained in the gnome install FAQ - here is a clip -
the devfs.conf changes fixed the problem.
To figure out which CD/DVD drive you will be using, run the following
command as root:
# camcontrol devlist
Your output will look similar to the following:
<QSI CDRW/DVD SBW-242 UD22> at scbus1 target 0 lun 0 (cd0,pass0)
The devices in parentheses at the end are important. You must make sure
the /dev entries for those devices are writable by the users that will
be using brasero, totem, rhythmbox, or sound-juicer. In addition to
those devices, /dev/xpt* must also be writable to your brasero, totem,
rhythmbox, and sound-juicer users. The following /etc/devfs.conf
configuration will achieve the desired results given the above devlist:
perm cd0 0666
perm xpt0 0666
perm pass0 0666
