+0 is equivalent to 1, which makes every frame a keyframe.
Values >300 are not recommended as the quality might be bad depending upon
decoder, encoder and luck.
For a strict MPEG1/\:2/\:4 compliance this would have to be <=132.

Always use the maximum number of B-frames (default).

Avoid B-frames in high motion scenes.

does both: It first reads the stats, then overwrites them.
You might want to backup divx2pass.log before doing this if there is
any possibility that you will have to cancel MEncoder.
