We determine the relative branching fractions of semileptonic B decays to charmed final states. The measurement is performed on the recoil from a fully reconstructed B meson in a sample of 362 million B{bar B} pairs collected at the {Upsilon}(4S) resonance with the BABAR detector. A simultaneous fit to a set of discriminating variables is performed on a sample of {bar B} {yields} DX{ell}{sup -}{bar {nu}}{sub {ell}} decays to determine the contributions from the different channels.
