CD permissions

[JB]

Glad to hear your eye surgery went well. Your chown
chmod commands worked but not on the first try. The
chown command gave me invalid group error so I changed
it from users back to root and also I made a group
called cdwriter and added users to the group. I
probably didn't do it quite right but it works and I
can use the CDburner without the root password! I
appreciate the help. Hopefully I did it correctly,
xcdroast seems to open up fine.
Thanks,
John
