Hi ;)
I have a strange problem: my external DVD burner (CIBOX 1016) works ok, excepting dvd recording speed. See the log:

So a 4.3G disk takes it 2h or even more.
When it comes to reading CD/DVD's, it works ok (full speed).
Any idea what's wrong?
thanks,
Michal |

dmesg output looks good and I can't help you much further. But I recall that here in the forums there are some posts that describe and deal with that problem.
Bye, Valentin. |
