Update:  Progress without success

I've recompiled my system and kernel with atapicam.
Executing 'camcontrol devlist' results in a listing of
my dvd burner as a scsi device.  Once I changed
'/dev/acd0c' to '/dev/cd0c' in /etc/fstab, I was able
to mount a cdrom in /dev/cd0c to /cdrom.

I executed the following as root ('./testfile' is a
short text file.):

>growisofs -Z /dev/cd0c -R -J ./testfile

Resutls:
Executing 'mkisofs -R -J testfile | builtin_dd
of=/dev/pass0 obs=32k seek=0'
:-[ LBA=0h, SENSE KEY=5h/ASC=30h,ASCQ=10h ]
:-( write failed: Invalid argument

Any ideas?

Thanks,
