Not possible to upgrade all packages

[mailing.list at srivastava.mailshell.com]

I get below. WHat is the solution? I tried Synaptic "Smart Upgrade"
but the problem is not yet resolved.

-----------
This means that besides the actual upgrade of the packages some
further action (such as installing or removing packages) is required.
Please use Synaptic "Smart Upgrade" or "apt-get dist-upgrade" to fix
the situation.

gstreamer0.8-lame
libavcodeccvs
libpostproc0
libxvidcore4
mplayer-386
