FC9 install DVD want additional disks

[Robert Holtzman]

I downloaded an FC9 installation iso (3.3 Gb) and burned it to a DVD. When 
I tried to install, it led me thru the media check which it said was fine 
and then asked to check additional disks. As far as I know, the 
installation DVD is complete in itself. It wouldn't let me proceed and 
kept asking for more disks. There was no apparent way to bail out.

Any pointers appreciated. Thanks
