Hi All, Why does k3b have the annoying habit of burning CDs at 2/3rd or less of the drive speed ? gtoast and xcdroast didn't seem to have this problem, but k3b does. My drive is 52x24x52 and gtoast used to drive it happily at 26x or 27x burn speed. k3b resolutely refuses to burn any faster than 16x on exactly the same hardware. Can I turn the Optimum Power Calibration off - after all, this is a desktop where power conservation, laudable though it is in a laptop running on batteries, is not an issue - and get it to speed back up ?
