the errors are do to rpmforge and epel being incompatible
you can not use both
vlc-1.1.13-1.el6.rf.i686 is the OLD rather very old vlc 1
the current VLC is vlc 2.1
Warning:
this might be a month long nightmare to fix
as in it might take all of Oct to fix this mess
or
it might only take one day
installing and configuring multimedia on cent is a VERY BIG NIGHTMARE!!!!!
i have "FUBAR'ed" many many installs doing that
it is VERY EASY to mess things up !!!
but once set up and working it is VERY stable
i would first start by uninstalling EVERY rpmforge rpm that is installed
-- this might leave you with a system that will NEVER EVER boot again !!!
so use caution
there might be only a few rpmforge packages
or
rpmforge might have replaces 50%+ of the base OS files with different versions ?
it is impossible to say at this point
this command will give you a list of packages to remove
if that lists 5 to 10 files then it might be a very easy fix
it it lists 20+ packages ....... not so easy
if it is 20 to 50 "rf" rpms them you might be able to "get away with" just removing the media related ? maybe?
VLC 2.0.1 is in the private repo "linuxtech.repo"
http://pkgrepo.linuxtech.net/el6/
and this also might be incompatible with other third party repos
-- USE CAUTION !!! --
also see the centos 6 forum post on vlc2
http://www.centos.org/modules/newbb/...38043&forum=56
also look into configuring "priorities" you have it installed
-- about the cent repos and the warnings with the third party ones

on that page is a link to "yum-priorities"
