Cannot Detect Fedora Core Cd on CD ROM

[kupoknight]

I have recently download FC3 on one of the mirrors on fedora.redhat.com.

md5sum are all ok.

Tried burning the iso's with Nero 5, Alchohol 120% and Burncdcc(4x) but still got the same error when trying to install.

The CD boots up and then goes to the first to that makes you choose what kind of installation you will use graphical or text.

I choose graphical and the first screen that it goes through is the one where you choose what language then next screen is where you choose what keyboard type then it lets me choose where the installation files are located Local CD ROM, HDD, NFS Image, FTP or HTTP.
I choose CD ROM and then after that I get an error that it does not detect the Fedora Core CD on the CD rom.

Can anyone help me?

Thanks.
