We study the decays B--->D(*0)pi(-) and B--->(DK-)-K-*0, where the D-*0 decays into D(0)pi(0), with the D-0 reconstructed in the CP-even (CP+) eigenstates K-K+ and pi(-)pi(+) and in the (non-CP) channels K(-)pi(+), K(-)pi(+)pi(+)pi(-), and K(-)pi(+)pi(0). Using a sample of about 123x10(6) B (B) over bar pairs, we measure the ratios of decay rates R-non-CP(*)=B(B--->(Dnon-CPK-)-K-*0)B(B--->D(non-CP)(*0)pi(-)=0.0813+/-0.0040(stat)(-0.0031)(+0.0042)(syst), and provide the first measurements of R(CP+)(*)equivalent toB(B--->(DCP+K-)-K-*0)B(B--->D(CP+)(*0)pi(-))=0.086+/-0.021(stat)+/-0.007(syst), and of the CP asymmetry A(CP+)(*)=B(B--->(DCP+K-)-K-*0)-B(B+-->(DCP+K+)-K-*0)B(B--->(DCP+K-)-K-*0)+B(B+-->(DCP+K+)-K-*0)=-0.10+/-0.23(stat)(-0.04)(+0.03)(syst).
