But is that the case with H264?  At least, according to the
documentation at

        The usefulness of B-frames is questionable in most other codecs
        you may be used to. In H.264, this has changed: there are new
        techniques and block types that are possible in B-frames.
        Usually, even a naive B-frame choice algorithm can have a
        significant PSNR benefit.
Are the ugly hacks you speak of required with mplayer, or in the x264
