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. tong |
