RHEL 5.5 w/updates DVD

Good Evening,

I was wondering if there's any tools for creating a DVD with RHEL 5.5 (we're working at moving towards 6.x....but we're lagging a little) with all of the updated packages from RHN?  I have a kickstart that works just fine.

We're trying to deploy a system for a customer that has no network access, and we'd like to give him the latest and greatest on his initial disk.  

First post, so if I screwed up blame the newb.

Thanks!
