  We present preliminary results of the analysis of B -> D0 h decays, with h =
pi, K and the D0 reconstructed in the channels K- pi+, K- pi+ pi+ pi-, K- pi+
pi0 and in the CP eigenstate K-K+, using data collected by the BABAR detector
during the years 2000-2002 at the PEP-II asymmetric-energy B Factory at SLAC.
We have measured the ratio of the branching fractions R = Br(B- -> D0 K-) /
Br(B- -> D0 pi-) = (8.31 +- 0.35 (stat) +- 0.20 (syst))% and the direct CP
asymmetry A(CP) = (Br(B- -> D0(CP) K-) - Br(B+ -> D0(CP) K+)) / (Br(B- ->
D0(CP) K-)+Br(B+ -> D0(CP) K+)) = 0.17 +- 0.23 (stat) +0.09 -0.07 (syst).
