Unable To Write To DVD

["Jeffrey D. Yuille" <jeffy5@xxxxxxxxxxxxx>]

Hello,

    I have an IBM ThinkPad T-30 and I recently bought a DVD+RW drive to 
use with it.  I had downloaded a DVD iso file from one of the Fedora 
Core 6 mirrors.  When I try to write the iso file to a DVD +R disk, I 
continue to get the error "The data does not fit on disk.  The .iso file 
is 3.3G and the disk is 4.7G.  What gives?  I am using K3b to burn the 
data to the disk but I continue to come up with this problem.  Has 
anyone else had this problem?  Any help would be greatly appreciated.
