New analytic and numerical results for the one-dimensional Domany-Kinzel cellular automaton are presented. Analytically we show that the qualitative features of the phase diagram, including the new phase recently found by Martins et al., can be predicted by going one-step beyond the mean field approximation. Numerically we find unusual finite size effects which make the extrapolations to the thermodynamic limit difficult.
