The output is adjusted to media in a drive, which is good to know when 
troubleshooting:
 
With K3b output is:
No media:
  (K3bDevice::Device) /dev/sr0:  Number of supported write speeds via 2A: 7 
  (K3bDevice::Device) /dev/sr0 : 8467 KB/s
  (K3bDevice::Device) /dev/sr0 : 7056 KB/s
  (K3bDevice::Device) /dev/sr0 : 5645 KB/s
  (K3bDevice::Device) /dev/sr0 : 4234 KB/s
  (K3bDevice::Device) /dev/sr0 : 2822 KB/s
  (K3bDevice::Device) /dev/sr0 : 1411 KB/s
  (K3bDevice::Device) /dev/sr0 Invalid DVD speed: 706 KB/s
  (K3bDevice::DeviceManager) setting current write speed of device /dev/sr0 to 0

Media in (DVD-RW 2x):
(K3bDevice::Device) /dev/sr0:  Number of supported write speeds via GET 
PERFORMANCE: 1
(K3bDevice::Device) /dev/sr0 : 2770 KB/s

With wodim output is:
No media:
  Maximum read  speed:  8467 kB/s (CD  48x, DVD  6x)
  Current read  speed:  8467 kB/s (CD  48x, DVD  6x)
  Maximum write speed:  8467 kB/s (CD  48x, DVD  6x)
  Current write speed:  8467 kB/s (CD  48x, DVD  6x)
  ...
  Write speed # 0:  8467 kB/s CLV/PCAV (CD  48x, DVD  6x)
  Write speed # 1:  7056 kB/s CLV/PCAV (CD  40x, DVD  5x)
  Write speed # 2:  5645 kB/s CLV/PCAV (CD  32x, DVD  4x)
  Write speed # 3:  4234 kB/s CLV/PCAV (CD  24x, DVD  3x)
  Write speed # 4:  2822 kB/s CLV/PCAV (CD  16x, DVD  2x)
  Write speed # 5:  1411 kB/s CLV/PCAV (CD   8x, DVD  1x)
  Write speed # 6:   706 kB/s CLV/PCAV (CD   4x, DVD  0x)

Media in (DVD-RW 2x):
  Maximum read  speed: 11080 kB/s (CD  62x, DVD  8x)
  Current read  speed: 11080 kB/s (CD  62x, DVD  8x)
  Maximum write speed:  2770 kB/s (CD  15x, DVD  2x)
  Current write speed:  2770 kB/s (CD  15x, DVD  2x)
  ...
  Write speed # 0:  2770 kB/s CLV/PCAV (CD  15x, DVD  2x)

BTW, according to wodim I should use CDs burned on DVD to have 
higher reading speed, 62x vs. 48x.
