I have a short trailer (MPEG2) that has the following information (taken from GSpot).

Sys Bitrate: 6000 kb/s VBR
Video bitrate: 6997 kbps
Audio bitrate: 384 kb/s

I have the following questions:

A. How can I take a different video and achieve a similar result as above?
B. Is sys rate also referred to as mux rate?
C. Why is the audio rate in kb/s and video in kbps? Surely this would make the audio bigger than the video.

Thanks,

D
