  We generalize a previous result concerning free martingale polynomials for
the stationary free Jacobi process of parameters $\lambda \in ]0.1], \theta =
1/2$. Hopelessly, apart from the case $\lambda = 1$, the polynomials we derive
are no longer orthogonal with respect to the spectral measure. As a matter of
fact, we use the multiplicative renormalization to write down the corresponding
orthogonality measure.
