Providing patched DVDs to potential users

A generic install of FC5 requires hundreds of megs of patches once installed, a particular frustration of mine, and I am sure it doesn't leave a good taste in the mouth of people trying out Fedora for the first time. Whenever I give out Fedora DVD images now, I make sure they are built form an updated install tree and that the will require no - or minimal - patching after install. Why isn't there updated monthly releases of the FC iso images? I think there should be, and I think whenever a DVD is handed out to the general public it should be up to date. Any thoughts? (and apalogies if this is the wrong group to post to). Rob Garth.
