Download Linux Repository (EPEL CENTOS)

i downloaded them by doing this:

rsync -avrt --progress rsync://mirror.cogentco.com/CentOS/6.7/updates/x86_64/ /ldata/repos/6.7/updates/x86_64/

rsync -avrt --progress rsync://mirror.cogentco.com/fedora-epel/6/x86_64/ /ldata/repos/epel/6/

then i used tar with bz2 to make them a little smaller.
Then used the Split command to make them fit on DVDs
split -b 1024m "file.tar.gz" "file.tar.gz.part-"

Then when they get over to the other side i used cat and piped to tar to extract the split files.

cat file.tar.gz.part-* | tar xj
