ok, just to clarify...
so -vbr=3:br=128 and abr:br=128 are synonyms?  as are vbr=0:br=128 and 
cbr:br=128?

you said cbr and abr are shortcuts for vbr=x and vbr=y...where x=0 and y=3?  
so if you set the bitrate method with vbr= and you choose either 3 (abr) or 0 
(cbr) for x, you still gotta specify the br= option, right?  but if you chose 
vbr=something other than 3 or 0, then the br= option is meaningless, right?

thanks again,
christopher
