FC4, K3B 0.11.23, growisofs 5.21, CD/DVD LG GSA 4120B.
I mostly use for burning DVD+RW, but in FC4 it is too slow. Max. speed is 1x, averige 0,7x (disks 4x). It doesn´t depend on a speed set in K3B, and the result is the same when i use growisofs in command line. Growisofs burns DVD-RW disks correctly. What could happen with DVD+RW? In FC3 it was OK.
Thank you for any advice.
