Description of problem:

When attempting an install/upgrade of Fedora 8 x86_64, I burned the Fedora 9
x86_64 ISO to a DVD+RW media.  The Sony BWU200S DVD+/-RW Blu-ray Disc Serial ATA
drive and Gigabyte BIOS was able to boot from the media fine and linux/anaconda
loaded up just fine.

However, when prompted what media to use for install, I selected CD/DVD and was
told no valid media was present or something to that effect.

Workaround:  By selecting Hard Drive, and typing in /dev/dvd, I was able to get
another error; however, it indicated something about /dev/sda1 not having valid
install media/files.  Yet, after backing up to the previous selection and then
selecting CD/DVD, the installation was able to continue?

Perhaps /dev/dvd doesn't get mounted in the right location initially or isn't
available?

How reproducible:

I attempted both an install and a later rescue and in both cases I had to use
the workaround.

Steps to Reproduce:
1.  Burn Fedora 9 (x86_64) install media to DVD+RW
2.  Attempt install and select CD-ROM/DVD as install media
3.  Observe no media detected.
  
Actual results:

The DVD+RW disk isn't in the proper location when coming through the Fedora 9
installer on the straight path.

Expected results:

Should be able to boot into the installer, select CD/DVD and continue.
