You might want to run `apt-get -f install' to correct these:
Sorry, but the following packages have unmet dependencies:
  libarts1-mpeglib: Depends: libxv1 but it is not going to be installed
  libarts1-xine: Depends: libxv1 but it is not going to be installed
  mpeglib: Depends: libxv1 but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a 
solution).

Problem seems to be package libxv, which will not installed properly.

Overwriting /usr/X11R6/lib/libXv.so.1.0 manually via cp works fine.
Does anybody have an idea, what to do, to make the package install properly.

Thanks in advance,
