how to use external USB DVD writer in FC5

[H.S.]

Hello,

I have an external DVD writer (Samsung SE-S164) connected via USB to my 
machine running FC5 ( 2.6.17-1.2187_FC5).

The system messages tell me that the writer is being detected:
kernel: usb 1-1: USB disconnect, address 3
kernel: usb 1-1: new full speed USB device using uhci_hcd and address 4
kernel: usb 1-1: configuration #1 chosen from 1 choice
kernel: scsi2 : SCSI emulation for USB Mass Storage devices
kernel:   Vendor: TSSTcorp  Model: CD/DVDW SH-S162L  Rev: TS05
kernel:   Type:   CD-ROM                             ANSI SCSI revision: 00
kernel: sr0: scsi3-mmc drive: 62x/48x writer dvd-ram cd/rw xa/form2 cdda 
tray
kernel: sr 2:0:0:0: Attached scsi generic sg0 type 5


and I get these devices created in my /dev:

However, I am not able to see this writer in Gnome. If I put a blank DVD 
in the writer, I do not get a window pop up asking if I want to burn a 
DVD and neither do I get an icon ("Blank DVD") on my desktop. I do get 
an icon if I put a blank CDROM in my internal CD writer. Any idea how to 
get the external writer working in a similar fashion?

I have hal (0.5.7.1), udev (084), dbus (0.61), and I belong to a single 
group (of my username red).

thanks,
