I am using 321 studios xpress, and it works just fine. Recently though, I get read times of 1 hr or better, and burn times of 30-40 minutes. It used to read the disc in 12-18 minutes, and burn in 12-13 . I have a 2.3g machine, and a pioneer 2.07 r/w drive. How come it slowed down, and is there any way to boost the speed?
