A study of the potential of the BABAR detector at PEP II to measure CP violation using the vector-vector channel B{sup 0} {yields} D*{sup +}D*{sup -} is presented. The decay mode, although not a CP eigenstate, is sensitive to the angle {beta} of the unitarity triangle, a fundamental measure of CP violation in the neutral B system. The decay mode B{sup 0} {yields} D*{sup +}D*{sup -} is reconstructed in a variety of channels and a study of the separation of the CP eigenstate contributions and extraction of the angle {beta} is presented. The contribution of this channel is compared with other similar channels, and the overall prospects for measuring the angle {beta} in the first years of BABAR running is summarized.
