I was just reading an lkml thread (flame fest) on this topic. I have
little experience with cdrecord on 2.6.* myself but have either of you
tried burning a cd using cdrecord with speed=[greater than] 16 as root?

If you don't call cdrecord as root, you will not be able to lock in
memory and to raise priority in order to prevent buffer underuns. In
addition (with Linux-18.104.22.168 or newer) you will not be able to send some
of the important SCSI commands mainly related to newer CD or DVD drives.
As a result, cdrecord cannot write DVDs or ultra speed CD-RWs or cannot
do other things....
