the palyers like vlc,xmms,movie maker,real player are not playing
these files,
so plzz give the link of source rpm of these or some solution......

look up mplayer

As I replied in the other thread that you posted, Fedora 8 is quite old and might not be supported anymore. Although it is probably doable to get those players work in F8, you'd be better off installing the most recent version of Fedora, which is F10

The answer is to go to your distro's forum on this site and look for a sticky near the top with instructions.

You will want to add a distribution that you will use for programs like k3b, vlc, mplayer, amarok, etc. For Fedora it is the rpm fusion site. Because of various reasons, such as a vidia driver not being open source, it can't be distributed in your download. After adding the community repository, you will be able to use your package manager normally.

The versions of vlc, xmms, etc. may be built without the support you want. Another issue is codecs. You can find and download many of the ones you need from this site:

I've seen some posts about RH9, but because FC has changed to using the rpmfusion site, older versions may no longer be available.

Update:
I just looked in the rpm.pbone.net website. It looks like Fedora 8 is still supported by freshrpms.
