Ignacio, the problem with size is probably because not having files available, what I used is https://alufis35.uv.es/Creando-plantillas-Jigdo-Jigsaw.html, translating it:

Having iso original file at path/iso/ and having the iso loopback mounted and available at path/tree/

We should run

jigdo-file mt -i path/iso/Fedora.iso -j Fedora-DVD.jigdo -t Fedora-DVD.template —uri fedoramirrors=http://whatevermirror path/tree/

After some checks, trying to download missing files it will create the template and .jigdo and hopefully, will be a small one ;)

Pablo
