[Centos] Knowing what packages come from where in apt/yum

Is there any way to find out what packages come from where? I have a
mixed CentOS with some Fedora updates (i know, I was just trying to add
ardour and a couple of multimedia programs so I can ditch windows), but
it has now become unstable, so I'd like to know what packages did I get
from fedora.

Is there an automatic way or should I just reinstall and installa the
few things I need?

Thanks

Gabriel
