And what repositories are you using outside of Ubuntu's repositories?
I assume you're just using Ubuntu's official repositories, because they
include all sorts of things that CentOS does not.
You don't get repository hell from just the official project's
repositories. You start experiencing repository hell when you add
repositories.
Now I've come close to no repository hell with Fedora Core + Fedora
Extras + Livna.ORG (the last redistributes "legally questionable"
packages). But that's Fedora, it's really built around 3rd party
repositories, but it still has its repository hell.
Debian users run into the same when they start tapping different
repositories for multimedia, etc... Hence why most Debian users start
looking at some of the Debian-based distros that just ignore legal
issues.

Exactly. Most end users don't want to know or care about it. Yet it's
a primary reason why there is "repository hell." Because those projects
and their repositories that want to only distribute what they legally
can means you have to go to other repositories to find software.
Hence the resulting problem.

CentOS does _not_ redistribute software that cannot be legally
redistributed. Debian is the same way, from the official repositories.
However, most of the popular, Debian-based distributions do redistribute
software that are "legally questionable." They win praise for this, but
they are a major liability nightmare.

In what regard? Other than the recent 4.2 snafus, what retrieve hell
have you experienced with _just_ CentOS (_no_ DAG)? I haven't
experienced too many performance issues with CentOS either.

But it affects many things, such as repository hell, which you run into
when you start tapping things like DAG in addition to CentOS. Things
you don't have to do with Gentoo or Ubuntu, because of their difference
in approach, design, legal considerations, etc...
Major reasons why I have to be _very_careful_ when I let Gentoo or
Ubuntu in the door of a place of business for indemification reasons,
but not CentOS, Fedora Core+Extras (although I do _not_ tap Livna.ORG in
that case), etc...

So why post this if you don't know how to help?

I don't know what to tell you, I haven't.
The reality is that CentOS is pretty popular, and may not have the same
support structure of some other projects. I don't know what to tell you
other than I've had _no_ issues with RHN -- even right after release.
All I know is that my RHEL3U6 and RHEL4U2 downloads virtually the day
after release were coming down at 300KBps (kilo_bytes_ per second) on a
business class DSL, and saturating a full T-1 at another location.
CentOS has been fairly good in speed of updates as well. I'm sorry you
haven't experienced this -- but you're mixing and matching so many
different things and offering no _solid_ insight that I really don't
know what you hope to accomplish?
Other than dropping another distro's name, which is all you're doing in
the end.
