If you go to the Archives page
, you will see a line which says "Click here to get the DVD via BitTorrent". This is not limited to subscribers, anyone can use it, so long as they are happy using bittorrent. Indeed the same link appears if you choose older magazines from the archive. I'm not sure quite how far back it goes, but certainly as far back as #163, which I've checked, and the torrent is available.
