  We analyze the pattern of normal modes in linearized Lorentz-violating
massive gravity over the 5-dimensional moduli space of mass terms. Ghost-free
theories arise at bifurcation points when the ghosts get out of the spectrum of
propagating particles due to vanishing of the coefficient in front of \omega^2
in the propagator. Similarly, the van Dam-Veltman-Zakharov (DVZ)
discontinuities in the Newton law arise at another type of bifurcations, when
the coefficient vanishes in front of \vec k^2. When the Lorentz invariance is
broken, these two kinds of bifurcations get independent and one can easily find
a ghost-free model without the DVZ discontinuity in the moduli space, at least,
in the quadratic (linearized) approximation.
