  Branching ratios and polarization amplitudes for B decaying to all allowed
pseudoscalar, vector, axial-vector, scalar and tensor combinations of D_s and D
mesons are calculated in the Isgur Scora Grinstein Wise (ISGW) quark model
after assuming factorization. We find good agreement with other models in the
literature and the limited experimental data and make predictions for as yet
unseen decay modes. Lattice QCD results in this area are very limited. We make
phenomenological observations on decays in to D_s(2317) and D_s(2460) and
propose tests for determining the status and mixings of the axial mesons. We
use the same approach to calculate branching ratios and polarization fraction
for decays in to two D type mesons.
