in this case, the external dvd drive is an LG GSA-H10N (which otherwise is a totally USELESS drive on a mac becuase it cant burn S/L or D/L ±R. Yet the same (PC burned) disc caused NO such problem when plyaed back from an *external* dvd drive that was _not_ ASAS! (apple shipped/supported). This disc failed on the internal (apple oem) dvd drive drive of TWO different macs - on both a powerpc mini as well as a intel C2D macbook!.

My circumstance: a D/L disc burned on a pc had a couple of files (when launched) that would cause the dvd drive to grind (endlessly) - any & all access to machine it would be impossible! * let the drive STOP all access to the disc (listen for whirring sounds)
