FC3 DVD iso question - actual size?

[Bob Hartung]

Would someone please enlighten me:

   The size of the DVD-iso of FC3 is listed as :
			 	    2466410496 bytes
   I have downloaded it three times from three
      separate sources and each time it is listed
      as size:                       2147483647 bytes

Needless to say it fails the MD5SUM test.  What is the cause of 
this behavior?  Sites used include mirrors.kernel.org amongst others.

Thanks

Bob
