From rpm.livna.org:

The merger between Fedora.us and Red Hat necessitated the removal of certain problematic packages (including but not limited to mplayer, xine, videolan-client and xmms-mp3) due to licensing issues or US software patent.

The open community of volunteers gathered in rpm.livna.org will continue to maintain those packages and everybody is free to contribute by sending new spec files and/or new packages.

See why you should use our nvidia video driver rpm packages instead of the nvidia installer. If you want to give it a try, you probably want to install the kernel-module-nvidia-$(uname -r) package. Be careful, only latest kernel is supported.
