Hi, up until recently i have been using Verbatim 2.4x discs for my backups( with close to a 99% success rate) but it seems as if they have stopped selling them. I tried the Verbatim 8x (mkm-003) discs and after several good burns i start to get failures at either somewhere around 80-90% or at finalize. I figured i would try the gold Windata discs that i see others using and i can't get one game to burn past 50%. Has anyone been able to use the cheaper discs with the Sony Optiarc burner and if so what settings should i change in Imgburn? I went ahead and ordered another burner just in case mine is going bad but now i'm wondering if i should have ordered an ihas instead. Thanks in advance for any suggestions and have a great day..
