CDVDinfo v1.3.5

CDVDinfo is a small program that tells you information about your DVD or CD-R/W drive.

Manufacturer, product ID, firmware version, and vendor specific information is displayed for both DVD and CD-RW drives. In addition to that region lock information, number of available region changes, number of manufacturer resets, current region code scheme, and supported DVD features are displayed for DVD-drives. For CD-RW drives also supported CD features are shown.

A nice piece of software that you might find valuable. See the software homepage for information on where to look for firmware updates for your drive.
