We report measurements of the branching fractions for the decays B -> D-s1 (2536) + (D) over bar ((*)), where (D) over bar ((*)) is (D) over bar (0), D- or D*-, and study of B -> X(3872)K with X(3872) decaying to D-*0(D) over bar (0) using a sample of 657 million B (B) over bar pairs recorded at the r(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider.
