What am I missing here? (sha256sum)

[Tom Horsley]

I just downloaded the f14 RC3 iso and the checksum file from
the same directory:

zooty> ls -l
total 3443676
-rw-r--r-- 1 tom users        740 Sep 21 00:59 Fedora-14-Beta-x86_64-CHECKSUM
-rw-r--r-- 1 tom users 3517335568 Sep 21 11:00 Fedora-14-Beta-x86_64-DVD.iso
-rw-r--r-- 1 tom users    5526034 Sep 21 11:00 temp.get

When I check the checksum, I get this:

zooty> sha256sum -c Fedora-14-Beta-x86_64-CHECKSUM 
Fedora-14-Beta-x86_64-DVD.iso: FAILED

When I calculate the checksum, I get this:

zooty> sha256sum Fedora-14-Beta-x86_64-DVD.iso 
24d764247508f18c19fdceb2d9f2bf714e3615a722f20c64a0ed365f3b7af885  Fedora-14-Beta-x86_64-DVD.iso

When I grep the matching file out of the checksum file I get:

zooty> fgrep DVD.iso Fedora-14-Beta-x86_64-CHECKSUM 
24d764247508f18c19fdceb2d9f2bf714e3615a722f20c64a0ed365f3b7af885 *Fedora-14-Beta-x86_64-DVD.iso

Why on earth does it tell me the checksum failed?
