I've spent a lot of time and bandwidth downloading some large files (linux distros etc) lately from torrents, and they keep coming out corrupted. Azureus and utorrent say they're OK when I force a recheck, and the rar'd ones unrar just fine, but the ISO files cannot be burned or mounted. Is this likely to be due to having interleaving turned off? I would have though torrent files with their rigorous checks would be ok, but perhaps not.

Thanks.
