Sony AD7170A Optical Drive will only Recognize CD's

I am running an early 2008 MacPro (OS X 10.7.5) which has a single Sony AD-7170A OPTIARC SuperDrive. The drive appears to recognize any blank or pre-recorded CD (and the contents can be played or accessed without any problems), but it does NOT recognize any blank or pre-recorded DVD's (e.g. my Snow Leopard OS X 10.6 DVD from Apple).

The OPTIARC drive has hardly been used and I wonder whether there is anything that I can try (e.g. cleaning of the optics, or a software update etc.) with the hope that it will recognise DVD's as well as CD's?

Thanks, Yan Lee

Radio Shack and other consumer electronics sellers sell a cleaning disc with tiny brushes on it for under US$10.

You insert the disc, call up Cd Player and it plays music and instructions, such as "please jump to track three". That swipes the brushes over the heads a little and does a passable cleaning.

Sometimes that is all that is needed.
