We present branching fraction measurements of twelve B meson decays of the form B {yields} D{sup (*)} D{sub s(J)}{sup (*)}. The results are based on {Upsilon}(4S) decays in B{bar B} pairs. One of the B mesons is fully reconstructed and the other decays to two charm mesons, of which one is reconstructed, and the mass and momentum of the other is inferred by kinematics. Combining these results with previous exclusive branching fraction measurements, we determine {Beta}(D{sub s}{sup -} {yields} {phi}{pi}{sup -}) = (4.62 {+-} 0.36{sub stat.} {+-} 0.51{sub syst.})%, {Beta}(D{sub sJ}(2460){sup -} {yields} D*{sub s}{sup -} {pi}{sup 0}) = (56 {+-} 13{sub stat.} {+-} 9{sub syst.})% and {Beta}(D{sub sJ}(2460){sup -} {yields} D{sub s}{sup -}{gamma}) = (16 {+-} 4{sub stat.} {+-} 3{sub syst.})%.
