So it seems.

Funny that it reports DVD 4x write speed since it's just a CDROM.

Even more funny is:

Maximum read  speed: 29551 kB/s (CD 167x, DVD 21x)
Current read  speed:   256 kB/s (CD   1x, DVD  0x)
Maximum write speed:   176 kB/s (CD   1x, DVD  0x)
Current write speed:     0 kB/s (CD   0x, DVD  0x)
Buffer size in KB: 5645

Impressive read speed. Too bad it's not noticed when I am actually using
the drive.. :-)
