I have never managed to use burncd with any drive.

In order to use atapicam, you must enable the pass? devices.  My 
devfs.conf contains:


# Commonly used by many ports
link    acd0    cdrom
link    acd0    dvd

# Allow a user in the wheel group to query the smb0 device
#perm    smb0    0660
perm    xpt0    0660
perm    pass0    0660
perm    pass1    0660

The xpt0 is left over from other experiments.  The pass? is required to 
allow general access to use of growisofs.
