Using 226x10(6) Upsilon(4S)-> B (B) over bar events collected with the BABAR detector at the PEP-II e(+)e(-) storage ring at the Stanford Linear Accelerator Center, we measure the branching fraction for B-0 ->(D) over bar K-0(+)pi(-), excluding B-0 -> D*-K+, to be B(B-0 -><<(D)over bar>K-0(+)pi(-))=(88 +/- 15 +/- 9)x10(-6). We observe B-0 ->(D) over bar K-0(*)(892)(0) and B-0 -> D-2(*)(2460)K--(+) contributions. The ratio of branching fractions B(B-0 -> D*-K+)/B(B-0 -> D*-pi(+))=(7.76 +/- 0.34 +/- 0.29)% is measured separately. The branching fraction for the suppressed mode B-0 ->(DK+)-K-0 pi(-) is B(B-0 ->(DK+)-K-0 pi(-))< 19x10(-6) at the 90% confidence level.
