I had this same problem not long ago and finally found an answer. This
is my apt preferences file:
$ cat /etc/apt/preferences
Package: *
Pin: release o=Debian,a=stable
Pin-Priority: 900
Package: *
Pin: release o=Debian,a=stable-updates
Pin-Priority: 900
Package: *
Pin: release a=squeeze-backports
Pin-Priority: 200
Package: *
Pin: origin "www.debian-multimedia.org"
Pin-Priority: 190
Package: *
Pin: origin "http://mozilla.debian.net";
Pin-Priority: 200
The key part for you are declaring the squeeze-backports and the
debian multimedia repos as I showed. This ensures squeeze-backports
takes precedence, but also packages installed from either repo will be
upgraded (when they get upgraded).
Hope this helps
Andres
