if you DISABLE the rpmforge repo and use the "--enablerepo=rpmforge " option you should be mostly safe in installing VLC
After you install the rpmforge repo
edit the /etc/yum.repo.d/rpmforge.repo text file
change " enabled=1" to " enabled=0"
yum --enablerepo=rpmforge install vlc
but there can be incompatibilities !!!
it is HIGHLY recommended to have installed and configured " yum-priorities" plugin ,first !!!
I am with "acid_kewpie" on this
(btw.... why?? that's a sign to me you're using the WRONG distro for your needs)
but it can be done , just use caution
put it this way
I have been running CentOS and ScientificLinux for YEARS
last year i ROYALLY MESSED UP my cent install ( BIG TIME - i had to reinstall )
installing mplayer and vlc with gstreamer
