Including final-state meson widths in the phase space of nonleptonic D decays changes some flavor-SU(3) branching-ratio predictions, most notably boosting D0 to K*0 eta' far above the experimental upper limit.

abstract
New data on the decays of the charmed particles $D^0$, $D^+$, and $D_s$ to $PV$ final states consisting of a light pseudoscalar meson $P$ and a light vector meson $V$ are analyzed. Following the same methods as in a previous analysis of $D \to PP$ decays, one can test flavor symmetry, extract key key amplitudes, and obtain information on relative strong phases. Analyses are performed for Cabibbo-favored decays and then extended to predict properties of singly- and doubly-Cabibbo-suppressed processes.

Finite width effects in nonleptonic D-decays
Including final-state meson widths in the phase space of nonleptonic D decays changes some flavor-SU(3) branching-ratio predictions, most notably boosting D0 to K*0 eta' far above the experimental upper limit.
