What reader are you using for running CD speed (drive manufacturer). You don't necessarily look at the max numbers. PI should have nothing higher than 200, and PIF never above 4. You really need to look at the PI avg and the PIF avg. Then there is the quality score. What number is that. For really good burns, avg PIF should always be in the areas of .1 to .2, and quality score should be at least 91, and preferably, in the mid to high 90's. Screen capture your CD Speed results, and post one here as a .png file if you can.
