all scans were done for one disc only, which is a MAM-A 4x DVD-R burned at 2x(max) in my NEC 2500a running firmware 1.07 (unhacked).

The media should be quite usable under any conditions I would think... but at the price, the fact that it only burns at 2x makes it pretty lousy compared to Taiyo Yuden which is cheaper and better quality (and faster!!)
(and yes, I do almost always run 8 or so tests on every disc I burn for quality reviewing....)
