vbv_maxrate is maxrate. You can't specify minimum bitrate, because there 
aren't any situations in which a minimum bitrate is appropriate. If 
maxrate > avgrate, why wouldn't you want easy scenes to compress as much 
as possible and leave more bits for the hard scenes? If maxrate == avgrate,
then the encoder must use constant bitrate in order to satisfy both 
constraints, so there's no need to separately specify minrate.
