Everything else looks great, and the fact that Microstudio IS running and reading and writing says your drivers are OK. You cleaned the CDR drive, so the media is the only thing left.
My recommendation is to buy our MTU Silver CDR media as it is the best in the world for duplicating CDG discs. However, there are some other threads in this forum that address other manufacturer brands that they have been successful with.
Since you didn't list a manufacturer, I STRONGLY suspect you have a "no-name" brand. My guess is you paid under $20 for 100 discs.
