HELP! CD Restrictions

Is there a way to restrict the CD/DVD drive for a mac user account?
I want someone to use an account on my Intel Mac but don't want her to be able to read CD/DVDs on it.

Anyone know how to do this?

Thanks in advance

Its in System Preferences > Accounts > click on the accpount and select Parental Controls

DVD access is in Finder and system

The account must be a standard not admin account, the above is for Tiger , Parental Controls may be somewhere else in Leopard
