I have the same problem with this drive. I am running ubuntu 10.4 alpha. My first CH08LS10 did
not burn under windows either, and I received a replacement for it this morning. While trying
to burn a DVD+RW and again getting a 0.1 to 0.3 speed I found the archive of this thread.
Based opun what I read, I looked for processes that tried to access sr0 and found several
children of udevd (they seem to be run in sequence):

/lib/udev/devkit-disks-part-id /dev/sr0
/sbin/blkid -o udev -p -u noraid /dev/sr0
/lib/udev/cdrom_id --export /dev/sr0

And yes, after stopping udev the drive speed jumped to 4x, which is the correct speed for this
particular dvd. So I suspect the udev related processes do not recognize the fact that the
drive is exculsively opened by k3b or its children.

Hope this helps (and somebdy can fix it).
