MD5 signatures of 5.1-RELEASE

I'm getting a wrong MD5 signature when downloading the miniinst image from 

ftp://ftp.freebsd.org/pub/FreeBSD/ISO-IMAGES-i386/5.1

Also, and this is really weird, the file sizes I see on a web browser are
different than what I get with a FTP client. Yes, I realize this is a
FTP URL but still, the file list view in Mozilla (both Firbird 0.6 on FreeBSD
and 1.2.1 on Linux) indicates files 7-8 megabytes smaller than a "ls" done
in a command-line ftp.

In any case, I don't care much about Mozilla's quirks - I just want
the miniinst ISO to match its MD5.
