As I understood b-frames, it makes the motion/bitrate-prediction better, 
because on that frames there will be looked forward and backward. The 
negative is that storing b-frames need more space as I-frames. 
So you will only have pros on fastmotion-scene-quality and size-prediction. 
At least b-frames have to work very well in the codec to get better results 
with that . The man of mplayer mention here not to use it since it is still 
buggy (at least the last time I RTFM ;o).

If I'm totally wrong please flame me ;o)
