From a sample of 232x10(6) Upsilon(4S)-> B (B) over bar events collected with the BABAR detector at the PEP-II B Factory in 1999-2004, we measure the B-->(DK*-)-K-0(892) decay branching fraction using events where the K*- is reconstructed in the K-S(0)pi(-) mode and the D-0 in the K-pi(+), K-pi(+)pi(0), and K-pi(+)pi(+)pi(-) channels: B(B-->(DK*-)-K-0(892))=(5.29 +/- 0.30(stat)+/- 0.34(syst))x10(-4).

Abstract
