If this worked fine and you are using now:
> -intra_vlc 0 -non_linear_quant 0 

then our option-handling decision was really very bad;-(
I suspect that  -flags2 +ivlc  became -intra_vlc 1
                       _^_                      _^_

Is that really so counter-intuitive?

Please test if that helps, if not please try to explain 
if the problem can be reproduced without mediainfo - we 
have to find the change introducing the problem.
