To remove a user [eg. john] from membership of a group [eg. accounts] use:

sudo deluser john accounts

And, to undo:

sudo adduser john accounts

So to match example (in other answer):

sudo deluser tachyons cdrom
sudo adduser tachyons cdrom    [to undo]

Do it in your risk

Take a backup of /etc/group

press ctrl+alt+t and type gksudo gedit /etc/group

Remove the users from cdrom(in this screenshot tachyons is the user name)

enter image description here

save the file and restart your pc

Added command-line alternative (potentially safer), as separate answer. – david6 May 11 '12 at 07:52
