[WYLUG-help] can't write cds or dvds with fc2

[Mike]

Can anyone help me with Fedora Core 2 once again, please. I have updated
the system using yum, got my old problems sorted out thanks to a lot of
help from WYLUG-help list members. Moving on to the next one, I can't
burn CDs - storing .jpg images and OO.o documents -  but haven't tried
DVDs yet. /etc/sysconfig/hwconf correctly lists the drives as follows,
although I am not aware whether the entry settings are fully correct:

-
class: CDROM
bus: IDE
detached: 0
device: hdc
driver: ignore
desc: "LITE-ON DVDRW SOHW-1213S"
-
class: CDROM
bus: IDE
detached: 0
device: hdd
driver: ignore
desc: "LITE-ON LTR-52327S"
-

hda and hdb are both HDDs and the box is new, with HDDs formatted by the
FC2 install CDs.

/boot/grub/grub.conf does not mention either drive (hdc, hdd) but then,
I don't think it should in FC2?

Which other files should I be looking at and what should they contain?

On trying to write to CD (same in either hdc or hdd) I first get a box
saying preparing to write to cd then I get an error box saying "error
trying to write to cd" with "ok" or "details" options. A click on
details offers:
