Browse to /System -> Library -> Frameworks -> DiscRecording.framework -> Versions -> A -> Resources -> DevicePlugIns and look for [YourBrandName]CDR.device-plugin. Load the file into HexEdit or some other hex editor and scan through for an identifier code for a supported CDR drive. For example, I searched for CDRW2410 and changed CDRW241032B to CDRW321040B. You can find out what the identifier string for your CDRW is if you have Roxio Toast; it's at the bottom of the main window for most drives.
Finder, Disc Copy, and iTunes all work now (all three previously reported no compatible CDR drive could be found). They even know I have a 32x drive, not the 24x drive whose identifier I replaced.
[Editor's note: This is an update to a similar hint. The path to the file has changed, but the process is similar.]
