growisofs problem

I've got a curious problem using growisofs on FBSD 5.2.1-RELEASE #0.
I'm using the following hardware (from dmesg):

acd0: DVDR <HP DVD Writer 530> at ata1-slave PIO4
cd0: <HP DVD Writer 530r VPS8> Removable CD-ROM SCSI-0 device 

Using the cd0 device (through atapicam) I can write to /dev/cd0 without
any errors, but I cannot mount the device to read it.  There is nothing
wrong with the DVD media (DVD+RW) because I can put it in another 5.2.1
system with a SONY DRU model DVD drive, mount it, and read it.  So the
bits are being written correctly by growisofs.

Here is the output when I try to mount the media in the HP 530r DVD drive:
# mount_cd9660 /dev/cd0 /mnt
mount_cd9660: /dev/cd0: Invalid argument

# mount_cd9660 /dev/acd0 /mnt
mount_cd9660: /dev/acd0: Invalid argument

Both devices are valid.  I can mount and read a commercial CDROM.  I have
not tried a commercial DVD yet.

Any thoughts?
