Simple steps to do so, Mind you, i created the following torrents to download all files, the first 3 (3 of 32 and 3 of 64) torrent files are simply the same ones as the ones posted on debian.org, the rest i am managing, if you want to use jigdo instead here are the simple steps.
apt-get update
apt–get install jigdo-file
wget http://cdimage.debian.org/debian-cd/7.1.0/amd64/jigdo-dvd/debian-7.1.0-amd64-DVD-1.jigdo wget http://cdimage.debian.org/debian-cd/7.1.0/amd64/jigdo-dvd/debian-7.1.0-amd64-DVD-1.template
jigdo-lite debian-7.1.0-amd64-DVD-1.jigdo
And in no time you will have the file, you can resume any time by issuing the command again
Happy downloading
