Well, at least you've gotten me onto something I need to investigate.

Experience has told me that the MD5 has should match for all copies of
an error-free download, file copy, and CD burn.  I was going to
demonstrate this when I found that they didn't for my copies of
Ubuntu 9.10 64-bit which I'd downloaded using BitTorrent.

$ md5sum -b /dev/cdrom

What on earth?!  Yes, I've checked another mirror as well.  Also
downloaded the .torrent file again, and Transmission verifies the ISO
100% complete.
