We present a study of the decays B⁰-->D⁰K^*0 and B⁰-->[overline D]⁰K^*0 with K^*0-->K⁺pi^-. The D⁰ and the [overline D]⁰ mesons are reconstructed in the final states f=K⁺pi^-, K⁺pi^-pi⁰, K⁺pi^-pi⁺pi^-, and their charge conjugates. Using a sample of 465×10⁶ B[overline B] pairs collected with the BABAR detector at the PEP-II asymmetric-energy e⁺e^- collider at SLAC, we measure the ratio R_ADS[equivalent][Gamma([overline B]⁰-->[f]_D[overline K]^*0)+Gamma(B⁰  -->[[overline f]]_DK^*0)]/[Gamma([overline B]⁰-->[[overline f]]_D[overline K]^*0)+Gamma(B⁰-->[f]_DK^*0)] for the three final states. We do not find significant evidence for a signal and set the following limits at 95% probability: R_ADS(Kpi)<0.244, R_ADS(Kpipi⁰)<0.181, and R_ADS(Kpipipi)<0.391. From the combination of these three results, we find that the ratio r_S between the b-->u and the b-->c amplitudes lies in the range [0.07,0.41] at 95% probability.
