i found a problem with the http://www.videolan.org/vlc/download-fedora.html page
It is for FC4 but we are now on FC6, so the title "VLC media player for Fedora Core 4" should have the 4 deleted.
The baseurl= lines need updating, either quickly by changing "$releasever" to "4" or updating the mirrors with a symlink of "5" and "6" to the 4 directory.
