To enable access to livna, do this:

rpm -ivh http://rpm.livna.org/livna-release-5.rpm

This should drop a yum repo configuration file in /etc/yum.repos.d/

Fedora Multimedia Installation HOWTO

Thanks for the help. But when I issued the command
# rpm -ivh http://rpm.livna.org/livna-release-5.rpm

The result is :
package livna-release-6-1 (which is newer than livna-release-5-8) is already installed
file /etc/smart/distro.d/livna.py from install of livna-release-5-8 conflicts with file from package livna-release-6-1
file /etc/yum.repos.d/livna-testing.repo from install of livna-release-5-8 conflicts with file from package livna-release-6-1
file /etc/yum.repos.d/livna.repo from install of livna-release-5-8 conflicts with file from package livna-release-6-1

I have also checked http://tldp.org/HOWTO/Fedora-Multime...WTO/index.html, and while trying to play the windows media files or real files it is asking to save the file instead of playing which means there is no default player mentioned in the browser setup. I work in Opera. So I think I have to connect mplayer as default player but mPlayer is not setting up.

If you look at the command it reads "release-5". The logical command when using Fedora core 6 would be "release-6".

In fact none of the information in that tlpd link seems updated to relect the current fedora version. Some of the information there may still be useful but be aware things change.

Other than that tidbit, I'm out-a-here. The combination of fedora and opera is to far outside my experience.

No regular fedora users reading this thread?

I sincerely thanks muddywaters for your helps. You have already helped a lot. I hope this problem will be solved soon. I tried to load Xine today from yum but due to dependency problem it failed to load properly. It is now giving dmux error. Thanks again for your help.
