Missing packages does not have to be a problem.

Download the debs manually and install (as root) with
dpkg -i -force-all {PACKAGE}.deb

Then for mplayer you need to just create symbolic links:

ln -s /usr/lib/libdbus-1.so.3 /usr/lib/libdbus-1.so.2

similar for libhildonfm... (sorry I don't remember the exact library names).

and run ldconfig

Good luck.
