We propose that some puzzles in the semileptonic decays of B mesons to the broad D** states could be clarified by studying at LHCb the corresponding decays with strange mesons B0S ? D-0. In particular, we point out that the nonleptonic decay B0S ? D-0p+ and the like, being Class I decays (where factorization is expected to hold), could be a first step in this direction. The interpretation of results in both semileptonic and nonleptonic decays will presumably be easier due to the narrowness of the D-0 state. On the other hand, we make a careful and detailed study of the experimental and theoretical situation in the case of the wide nonstrange D** case, and we update previous analyses.
