I own this burner now has about 3 months and have now probably close to 100 blanks fired all of whom were completely burned in order. I used initially Ritek G04, before I switched to DVD + R Ricoh (2.4x) and now on DVD + R switched from Ritek (4x). Pioneer can describe each blank with the specified speed, many other burners write certain varieties blank only at a slower rate than specified. Pioneer is on the DVD +/- R sector really a "pioneer", which is also reflected in the appliance, the burner will burn everything you put him in the ark. I would not hesitate to again resort to pioneer when I wanted to buy a new burner.
