Uncomment these, or at least the first one.  :-)

You might also be having some issues with SATA support under 4.9 with the ICH5 
controller if you were using these rather than a normal ATA port; it might be 
the case that 5.2.x would work better for you.  People are actively working to 
improve this area.

Can you a burn a CD on cd1?  What device are you using with cdrecord, via SCSI 
or are you specifying the device as ATAPI:...?

growisofs tries to open the device for reading to check the status of things 
like the media, before it tries to write anything.

The output of "camcontrol devlist -v" might also be interesting...
