I only know of two official versions. The DE and the EN. If you are downloading a Spanish version, it must be a re-mastered disk.

I don't think you can just create a torrent from someone's FTP site. You would probably need to have access to the file and permissions on the server. You can start one locally from your own machine or server. I haven't tried to do one from an FTP Mirror, so I can't be absolutely sure, but it does not sound likely.
