We report a measurement of the branching fractions of B -> D**l(-)(v) over bar (l) decays based on 417 fb(-1) of data collected at the Y(4S) resonance with the BABAR detector at the PEP-II e(+) e(-) storage rings. Events are selected by fully reconstructing one of the B mesons in a hadronic decay mode. A fit to the invariant mass differences m(D-(*())pi) - (m(D-(*())) is performed to extract the signal yields of the different D** states. We observe the (B) over bar -> D**l(-)(v) over bar (l) decay modes corresponding to the four D** states predicted by heavy quark symmetry with a significance greater than 5 standard deviations including systematic uncertainties.
