  Using a sample of 227 million $\Upsilon(4S) \to B \bar{B}$ events collected
with the $BABAR$ detector at the PEP-II $B$ Factory in 1999--2004, we study
$B^- \to D^0 K^*(892)^-$ decays where $K^{*-} \to K^0_S \pi^-$ and $D^0 \to
K^-\pi^+, K^- \pi^+ \pi^0, K^-\pi^+ \pi^+ \pi^-$ (non-CP final states), $K^+
K^-, \pi^+ \pi^- (CP+$ eigenstates), $K^0_S~\pi^0, K^0_S \phi$ and $K^0_S
\omega (CP-$ eigenstates). The partial rate charge asymmetries
$\mathcal{A}_{CP}$ and the ratios $\mathcal{R}_{CP}$ defined in the literature
as the sum of the $B^+$ and $B^-$ partial rates to a charged $K^*$ and a $D^0
CP$-eigenstate divi ded by the $B \to D^0 K^*$ decay rate, %of the

$\gamma$ of the CKM unitarity triangle. We measure:
  \mathcal{A}_{CP+} &=&-0.09 \pm 0.20 (stat.) \pm 0.06 (syst.)
  \mathcal{A}_{CP-} &=& -0.33 \pm 0.34 (stat.) \pm 0.10 (syst.) (+1.15 \pm
0.12) \cdot (\mathcal{A}_{CP-} - \mathcal{A}_{CP+})
  \mathcal{R}_{CP+} &=& +1.77 \pm 0.37 (stat.) \pm 0.12 (syst.)
  \mathcal{R}_{CP-} &=& +0.76 \pm 0.29 (stat.) \pm 0.06 (syst.) ^{- 0.04}_{-\
0.14}
  The third uncertainty quoted for the CP- measurements reflects possible
interference effects in the final states with $\phi$ and $\omega$ resonances.
All results are preliminary.
