[CentOS] Created a DVD from Gnome Desktop -CentOS-5.3

I am trying to put the dvd iso image of CentOS-5.4 onto a DVD.  I
have an LG multi-writer installed.  I have used this device on this
host to created CDs in the past but this is my first attempt at
creating a dvd.

When I put a blank DVD-R media in the drive then I see a desktop
icon for "CD-ROM Disc" created.  When I open the bittorent folder
and click on the iso image "CentOS-5.4-x86_64-bin-DVD.iso" then I am
prompted to open the image with "CD/DVD Creator".  When I do this
then I get a new window opened with the image file in the lower
portion and an entry at the top labelled:

CD/DVS Creator Folder and a button labled "Write to Disc"


When I click on write to disc I am prompted to either create from
image or create from file.  I select image and am propted for the
speed. I select maximum possible (the default) and press the write
button.  I get this error:

Insert a rewritable or blank disc

Please put a disc, with at least 4.3 GiB free, into the drive.  The
following disc types are supported:
DVD+R DL, DVD-RAM, DVD-R, DVD-RW, DVD+R, DVD+RW

I get the same thing if I use a DVD-RAM.  What is going on?  I have
used the same model dvd writer on a MSWindows stations and have
created readible dvds therefrom.

Any ideas on how to proceed?
