It should be

applydeltaiso Fedora-16-Alpha.RC4-x86_64-DVD.iso
Fedora-16-Alpha.RC4-x86_64-DVD_netinst.diso Fedora-16-RC4-x86_64-netinst.iso

(In other words, oldiso is the new DVD, diso is the DVD->netinst diso, newiso is
the new netinst.)

BTW, "fread: Success" is a really bad error message - you only see it when
oldiso is shorter than expected. I know why it happens (it's from a perror()
call following fread(), which the fread man page points out is wrong) but
haven't filed a bug on it yet.
