[Hampshire] Corrupt files over bittorrent

Hi all

Has anybody had any problems downloading files via BitTorrent? I've downloaded a couple of isos and neither are coming up with the right md5sums. I'm not sure how common corrupt files are over torrent - so if I've just been unlucky - then fine - but otherwise I think I might either download via ftp or buy the disk (Slackware 11).

Cheers
Rob
