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.

$ wget -q -O - http://www.gtlib.gatech.edu/pub/ubuntu-releases/karmic/MD5SUMS
dc51c1d7e3e173dcab4e0b9ad2be2bbf *ubuntu-9.10-desktop-amd64.iso
$ md5sum -b ubuntu-9.10-desktop-amd64.iso
82a867bbfe856e50f4dcec9d7585193c *ubuntu-9.10-desktop-amd64.iso
$ md5sum -b /dev/cdrom
f20000abc83e2b07cff2e1e6bddf44d3 */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.
