I lost my original iso of the 4.0.2 cd and I wanted to make another copy (my original copy is busy installing gentoo on another machine right now) so I downloaded the bittorrent tracker from the official site at http://torrent.unix-ag.uni-kl.de/ . Bittorrent said the download was completed successfully. I checked the md5sum anyway, and it failed. I thought "whatever" and burned a cd anyway. When I used the testcd cheatcode it also failed on KNOPPIX/KNOPPIX. What's up with that?

Are the md5sums wrong for some reason or did I really get a bad download through bittorrent?
