unboot vs my DVD burner

[Michael Hennebry]

I tried to burn a F17 install DVD and thought that I had failed.
The result would not mount and if I asked right I was told no medium in drive.
Forgetting it was there, I did a reboot.
The BIOS found it with apparently no trouble.
Anaconda started, I pushed the eject button and then the reset button.
The same drive can read a DVD written by a stand-alone burner
and a DVD previously written by the same burner.
Any idea what gives or what I should look for?

The motherboard is a D865GBF.
The burner is a Toshiba SDR5112.

Yes, I know F14 is EOL.
I've managed to install F16 and F17,
but I haven't gotten either of them to work.
That is why I mentioned the motherboard without prompting.
