Hardware Correction: How to change DVD write speed

[Rubberman]

Ok. I understand that. I also write my CDs and DVDs at some speed less than the maximum for the same reasons. As I suggested before, have you tried the command line burning tools and specify the exact speed you want, such as 1x?

Hi Rubberman

A.
k3b starts at 1x but reassigns writing mode to 4x.

So its IMPOSSIBLE?

It may be just possible that this is the lowest speed possible on this particular piece of hardware.

Hi jayd512

I tested liveCD of ubuntu 804. It gives me write speed of 1x.

Moreover I used ubuntu 804 for two years and wrote DVDs at 1x without any problem with same hardware.

So its IMPOSSIBLE?

As you noted in another post, 8.04 was able to record at 1x, assuming the same hardware, so likely something has been done with either the burning software, or the driver. In any case, I'm afraid that I don't know enough to do more than suggest that it is possible, but I don't know how... sorry.
