Has someone a working yum.conf that additionally includes FreshRPM, DAG e.t.c. for the most important rpm's such as mplayer, xine e.t.c? The site http://www.fedorafaq.org/ does not provide such a file for FC3 yet.
In FC3 the idea with the new yum is not to have one big yum.conf with all your repos in, but to have a small yum.conf file with repository-independent options in it (the one that comes as standard with FC3 is fine if you change distroverpkg from redhat-release to fedora-release) and then separate files in /etc/yum.repos.d for each repo. This allows you, for instance, to set up the repo for FreshRPMS by doing just:
rpm -Uvh http://ftp.freshrpms.net/pub/freshrpms/fedora/linux/3/freshrpms-release/freshrpms-release-1-1.fc.fr.noarch.rpm
I expect the other repos will create equivalent RPMs before much longer. In the meantime, you can set up a repo file for Dag as follows:
If you don't already have Dag's GPG key installed: rpm --import http://dag.wieers.com/packages/RPM-GPG-KEY.dag.txt
Then, create a file /etc/yum.repos.d/dag.repo
[dag] name=Dag RPM Repository for Fedora Core $releasever baseurl=http://apt.sw.be/fedora/$releasever/en/$basearch/dag enabled=1 gpgcheck=1
