You can determine the bitrate of an MPEG ES (audio / video / etc.) by 
looking at the ES rate field after the PES header, assuming the ES rate 
flag is set.  You can also look at the i_mux_rate data member of the 
VLC stream_descriptor_t structure.  I realize that this is a bit short, 
i'm just kind of tired right now and don't have a running VLC instance 
handy, so I don't know if the GUI displays this info anywhere.  If you 
need more info on how to find this out, i'll be glad to assist in any 
way I can.

John
