Thanks Darren & Hervé for your kind explanation.

Summary for now:

- Darren suggest to lower -b but Hervé said it will cause buffer
underflow.
- Hervé suggested to use VBR, which is almost the same as what I used
(-b 3600 -maxrate 4500 -sameq), but I was told that it is CBR.

hmm.., there seems to be still some confusions going on.
