Hey dudes, I have today burned a .iso (Hulk) file with 16x speed and guess what? I have 97.23% quality rating I used ImgBurn and Verbatim with a Poineer DVR-115D Someone thought I can advise them (i.e. the community) to burn on 4x speed. While burning on 16x speed is much better indeed. I also discovered that, while burning on 16x speed the really burn speed is actually not more then 9x or 11x speed!
