I also have this problem with a LG 16x DVD-RW drive, P4 1.8 Ghz. Tunning hdparams increased a bit the speed to 2x.
Changing the k3b process priority to 19 increased further the speed to 6x (but it is still far from 16x). I guess the problem is related to the CPU usage: hdparams reduces CPU usage, and renice gives more CPU to k3b, so both increase the burning speed. -- Dapper: k3b slow dvd burn speed https://launchpad.net/bugs/31709 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
