Desktop Environments on Fedora 18 - 64 Bit

Hi Friends,

I have installed Fedora 18 (64 bit version) two days back. At the time of installation, I selected developer machine as the option. I now have Gnome and Kde environments. Now, if I want to install Xfce, Lxde environments, can anybody help me how to do that without using internet connectivity?

I have the DVD with me and want to use the rpm files present in the DVD rather than using yum utility which will connect to internet.
