I have an another problem: I have an LG 16x DVD writer, and use it with k3b on debian with 4x writeable discs, but it writes only 1.5x speed. My G3 CPU is on 100% over the process. I tried to use ide-scsi drivers in kernel parameters, but it does not work. Any ideas?

I had this problem as well. But the problem solved iself. I believe it
was some kernel issue. What kernel are you using? Try latest ones
2.6.8 or 2.6.9.

I have found the soulution without compiling a new kernel: you should use ide-scsi module for DVD writing, which doesn't use so many CPU and is a lot faster. There is how:

First of all, test you have the module:
Code:
(if you get no errors, you have it)

Then you should add the following line to /etc/modules (not .conf!!):
Code:

Then add some parameters for your startup (e.g. in bootmenu or in commandline in OFW):
Code: (hdc is for your DVD-RW)

(mine looks like this: /boot/vmlinuz-2.4.25-powerpc root=/dev/hda4 hdc=ide-scsi hdd=ide-scsi video=radeon:1024x768@85)

Then if everything is OK, you reach your DVD-RW as /dev/scd0.


Good luck!
