We calculate collective modes and study stability of the flux-flow regime of the Josephson vortex lattice driven by a transport current perpendicular to the conducting layers of a layered superconductor in the limits of high and low magnetic fields. The sliding triangular vortex lattice is found to be stable at small velocities up to a critical value. At larger velocities the uniform motion of neither triangular nor quadrangular vortex lattice is stable. In the flux-flow regime we calculate intensity of the radiation emitted from a semi-infinite sample. The radiation power exhibits a large maximum at the lattice velocities corresponding to the Josephson plasma frequency. However, this maximum can be observed only in large enough magnetic field. We demonstrate that the convective term in the equation of motion for the lattice displacement that was reported to be responsible for dynamical phase transitions is small in high magnetic field.
