I pretty much aviod that by using priorities above 1000 which will 
install a package from a repository even if it is a downgrade.

I'm not sure on the semantics of upgrading and priorities below 1000.  I 
will have to do some experiments.

Check out the apt_preferences manual page.

It's interesting that I was able to switch from mplayer from livana to 
mplayer from dag by changing the priority and running apt-get dist-upgrade.

Now I will have to learn how yum handles repository priorities...
