Do you have another DVD (MS Windows or something else) that you can boot off of?
I wonder if you can boot the Live CD for CentOS 5.2 and run from
that.. That would show you whether or
not this OS will run on your HW. Do you have any Diagnostics you can
run on your DVD
Reader/Burner, to see it working properly? If not, possibly you can
get the Diagnostics from the
manufacturer of the drive or if it was installed in your PC when you
bought it, from the manufacturer
of the PC.
