[CentOS] Safe to use gstreamer repository for RH or Fedora?

I'd like to install "Gstreamer" so that I can get MP3 support in
Rhythmbox. At least, I'm led to believe MP3 support comes with
installing Gstreamer from Rhythmbox's FAQ.

But when I get to the Gstreamer download page:
http://gstreamer.freedesktop.org/download/

... it says:

"Do not compile from source yourself unless you are certain you have to
or want to"

Okay, fine. So I look for an RPM. But it doesn't have those, it only has
repositories for Fedora and Red Hat.

A while back I messed up my system by installing repositories for
Fedora, so I'm wary of doing that kind of thing again.

I tried a YUM search for gstreamer to see if it was available on DAG,
but no luck there.

Does this mean I fall into the category of compiling myself because I
have to? The warning on the web site makes it sound like this is
something for experts to do.
