[15:0] The register is used against the bi-directional mode in
the weighted macroblock mode decision.
Mode decision will be done by comparing 1)
uni_direction_cost and 2) bi_direction_cost +
ENC_COMMON_BI_DIRECT_BIAS.
If the macroblock type is INTRA, this register is of no
effect.
To disable this option, set
ENC_COMMON_BI_DIRECT_BIAS to zero.
This register is effective in MPEG4 encoding only.
