Also for real CBR I always suggest a low vqsquish, eg. 0.1 (vqsquish name is 
from mplayer, I don't know what it's called otherwise). It sure makes the 
encoding CBR like, but maybe setting the max/min rate is enough - I don't 
know because I stumbled upon vqsquish a long time ago when the rate/buffer 
management was still lacking.
