I got my UJDA720 working again for CD/CD-R/CD-RW/DVD by
1. running this driver update package from roxio's web site
2. Uninstalling the driver for the device in the Device Manager
3. When I restarted, letting XP search for a driver for the "new hardware device."
It finds the driver files installed. Specifically, Device Manager now shows the files Cdr4_XP.sys and Cdralw2k.sys being used by the device. Othere than those two from Roxio and generic CD drivers from Microsoft, there is one other driver loaded from Veritas software called PxHelp.sys. I don't know how this one came to be on my system, whether it comes with XP, or whether it is actually required.
