Setup does not recognize valid CD

Re-installing Windows XP. Setup loads fine, but says it cannot read from the inserted CD or it is not a valid Windows CD. I have 2 separate OEM CDs and neither will work. One copy is brand new, never used. The CD drive reads any other CD just fine. Any suggestions would be greatly appreciated.
 
No. I believe I found the issue though. They are 2002 versions before SP1 and the tower has SATA drive. Tried XP w/SP3 and it worked like magic. ;-)
