Yes, But I must ask again, rpm is using xz compression, but can it be recompressed again with xz, xz is already present in Fedora 11/Fedora 12/Fedora 13 Alpha/Fedora Rawhide and 7zip can open/extract the files too.   The rpms are xz compressed but the isos are not.  That is what I am asking, or is it too much compression?  When is so much too much?

Thanks for taking the time to answer :)

Regards,

Antonio
