We have studied all decays of the kind ({ital D},{ital D}{sub {ital s}}{sup +}){r arrow}{ital VV} in two models: an SU(3)-symmetry model with nonet symmetry and a factorization model, and the inclusion of final-state-interaction phases. We show that the factorization model makes predictions in agreement with data, with fewer free parameters. Detailed predictions for all decay modes are made and the two models contrasted.
