DVDs are still somewhat of a black art I think. "Good media" sometimes doesn't mean anything, as it's more what media works better with what kind of drive. It sounds to me like whatever media you're using is not being liked by the drive, but that the standalone (which has a different laser) likes it just fine. Is there any way you can find out the make of your drive? If so, go to the www.dvdrhelp.com and look through their list...maybe you can see some other people who have had problems with that combo of hardware/media.

Since it plays fine on your standalone, my inclination is to say that the disc is fine and the drive simply doesn't like it.
