The Yammie tries to do it intelligently and the 2200 is too new to tell yet whether or not it can burn convincingly at high speed. But the media has to be branded with the 20x speed on the box for that to work.

The technical issue is the amount of time that the 'bit' being burned is exposed to the laser. The laser has to be strong at high speed and thus the media has to be good. Take care.
