If the CD/DVD device was formatted using the newer Live File System and the OS sees the device as a Removable Media, the Removable Storage Protection (RSP) rule will trigger on files being written to CD/DVD devices.
If the old Mastered File System was chosen, then the (RSP) rule cannot be used. For this scenario, you would use the Application File Access Protection (AFAP) rule instead. This rule may be used to monitor applications like Nero, Roxio etc. to trigger on files access.
Why would the user use applications like Nero/Roxio if the intent is not to burn CD/DVDs.
The AFAP rule support content only in a later 9.2 version. You would want to move to the 9.2 version that supports this feature or 9.3.
