RPMforge is a collaboration of Dag and other packagers. They provide over 5000 packages for CentOS, including wine, vlc, mplayer, xmms-mp3, and other popular media tools. It is not part of Red Hat or CentOS but is designed to work with those distributions. See also Using RPMforge and Repoforge.
Note: Because this repository is NOT part of CentOS, you should direct support questions to its maintainers at the Repoforge Users mailing list.
Packages are supplied in RPM format and in most cases are ready to use. The default RPMforge repository does not replace official CentOS base packages.
