Brasero does not honor speed setting

Brasero 0.7.0 has a workaround this problem/bug. I suggest you to try out it's available on hardy.
Sometimes cdrecord/wodim set's a recommended speed for burning so it's not just a brasero problem.
Please try 0.7.0 i belive it will work for you.

Brasero won't honor speed settings in two situations:

(1) Selecting a non-working speed. For instance, a drive is only able to burn at 10x, 16x and 24x, and K3b is correctly showing this, BUT Brasero doesn't know the working speeds, as it *only* tests for the MAXIMUM speed, then it lists all the "theoretically possible" speeds down to zero, with a 2x step. So you'll have 52x-50x-...-24x-22x-20x-...-2x. If you select 24x, it will honor it. If you select 28x, it will disregard it and it will burn at the maximum speed, whatever that means.

(2) Selecting a (bug) odd speed: 1x, 3x, 5x, etc. See upstream bug http://bugzilla.gnome.org/show_bug.cgi?id=525501 in that case.

This bug was fixed in the package brasero - 0.7.91-0ubuntu1
