000003327 520__ $$aWe report results of the branching fractions for a number of charm B decays including $\APBzero \to \PD^{*+}\Ppiminus$, $\APBzero \to \PD^{*+}\PKminus$, $\APBzero \to \PDplus\Ppiminus$ and $\APBzero \to \PDplus\PKminus$ all measured using $772\times 10^6$ B-meson pairs recorded by the Belle experiment at the KEKB asymmetric-energy $e^+e^-$ collider. The measurements provide a precise test of QCD factorisation. We also report preliminary results for the branching fraction $\mathcal{B}(\PBplus \to \PD^{(*)}_s(\Peta,\PKs)/\PDplus(\Peta,\PKs))$ and the time-dependent CP asymmetry in $\PB \to \Petac\PKs$. The latter measurement provides information on $\sin2\phi_1$.
