  We re-examine and extend a recent analysis which showed that the rho-omega
mixing amplitude cannot be unambiguously extracted from the pion
electromagnetic form-factor in a model independent way. In particular, we focus
on the argument that the extraction is sensitive to the presence of any
intrinsic omega_I -> 2pi coupling. Our extended analysis confirms the original
conclusion, with only minor, quantitative differences. The extracted mixing
amplitude is shown to be sensitive to both the intrinsic coupling omega_I ->
2pi and to the value assumed for the mass of the neutral rho meson.
