Hi,

I found my bug and now I can tell you about the very first results of 
"non-heuristic adaptive quantization". In my extensive tests with the huge
data set of full 10 frames of the foreman sequence in QCIF (176x144),
I achieved the immense quality improvement of 0.0002 in PSNR 
(from 37.57531 to 37.57551) when at the same time REDUCING bitrate by 
incredible .0517% (from 1934 bytes to 1933 bytes). 

Well... maybe not _too_ impressive so far, but at least it works now. 

;-)
