We present constraints on the angle {gamma} of the unitarity triangle with a Dalitz analysis of neutral D decays to K{sub S}{pi}{sup +}{pi}{sup -} from the processes B{sup 0}{yields}D{sup 0}K*{sup 0} (B{sup 0}{yields}D{sup 0}K*{sup 0}) and B{sup 0}{yields}D{sup 0}K*{sup 0} (B{sup 0}{yields}D{sup 0}K*{sup 0}) with K*{sup 0}{yields}K{sup +}{pi}{sup -} (K*{sup 0}{yields}K{sup -}{pi}{sup +}). Using a sample of 371x10{sup 6} BB pairs collected with the BABAR detector at PEP-II, we constrain the angle {gamma} as a function of r{sub S}, the magnitude of the average ratio between b{yields}u and b{yields}c amplitudes.
