The decay of charmed mesons into pseudoscalar ([ital P]) and vector ([ital V]) mesons is studied in the context of nonet symmetry. We have found that it is badly broken in the [ital PP] channels and in the [ital P] sector of the [ital PV] channels as expected from the nonideal mixing of the [eta] and the [eta][prime]. In the [ital VV] channels it is also found that nonet symmetry does not describe the data well. We have found that this discrepancy cannot be attributed entirely to SU(3) breaking at the usual level of 20--30 %. At least one, or both, of nonet and SU(3) symmetries must be very badly broken. The possibility of resolving the problem in the future is also discussed.
