Glad to hear you're trying out Fedora
By FC1 Test 1 do you mean Test 1/2 of Fedora 7?
As far as third party repositories go, I usually use FreshRPMs for attaining anything else that I don't feel like building from source. I seem to have had great success with FreshRPMs in the past. For whatever reason, I generally try to avoid Livna. As far as ATRPMs go, I use them on my MythTV Fedora boxes. Be forewarned that ATRPMs will try to replace some of the system packages with their own.
