You've got a couple of problems:

1. FC5 hasn't been supported for a while, so the orig official repos are probably gone; FC is on v10, v11 in beta.
2. 3rd party repos like atrpms etc have been collected and merged for the up to date systems. iirc, its called rpmfusion or some such now.
ah ... http://rpmfusion.org/RPM Fusion; doesn't mention atrpms but you prob don't need to use that one. Its a merger of Dribble, Freshrpms, and Livna.

Thanks but I'm on FC8 not FC5. Also when I try the link you've provided I get -

RPM

This page does not exist yet. You can create a new empty page, or use one of the page templates.

I have heard about rpmfusion but I've not been successful in tracking down a repo config file for it.

I have had problems with unresolvable dependencies and conflicts and I think it all started when I uninstalled the native FC8 firewire support and installed the IEE1394 support from livna so I could use my Canon DV camcorder and dvgrab etc. Not sure why this would happen but it could just be coincidence.

From the looks of it, you have seriously misconfigured your YUM repositories on your Fedora 8 install.

The 'development' repositories are for users who want to use the most current (always changing) packages that Fedora developers are developing. This should almost never be enabled on a system, unless you want to use an unstable/development Fedora. The 'testing' repositories are for packages that have moved from 'development' but not yet ready for normal usage. The 'source' and 'debug-info' are also completely useless unless you are a developer or want to modify/recompile/debug/test Fedora software.

I am not even sure that you can maintain your Fedora 8 install (keep in mind that Fedora 8 is no longer supported). If you have accidentally installed from different repositories it can cause all sorts of mess that might not be able to fixed, since this combination is not supposed to be used.

I would recommend a clean install (preferrably a newer Fedora). Or if you want to preserve your install, you will need to disable all the unnecessary repositories and fix/re-install the apps that are misbehaving. That might just be too much work though.

Yeah I thought that might be the case. I'm not one for updating for the sake of it but I guess it's time for a fresh install now. Oh well, there goes another weekend.
