My past experience has shown that, on rare occasions, certain brands of media don't get along with certain brands of hardware.
In addition, I have a PC with a CDROM/DVD player that will not
load the OS from a CD. I have
to use a DVD. (I don't know why)
I am just stating facts and spewing a few ideas worth trying out.
Change the media type/brand and see if that makes any difference.
I wish you the best of luck.
