The problem is the Optimum Writespeed Control, if you have it on it only burns as fast as it can with the inserted media, if you have 24x certified media then it'll burn 24x even with OWC on. Like Don66 said, just go to Recorder, Choose Recorder, then Options, to turn OWC off. I still havent found out how to do that with CloneCD, if anyone knows how to bypass the speed check which most burners do in CloneCD, then please let us know.
