Hm, maybe you could try to increase the compression ratio - then the
differences should be more visible. I think pp=ac is better than pp=de
but it is also stronger. The postprocessing I like most is pp=ac whith

Do not add too much noise, doom9 is going to analyse single frames. It
would be bad if they would write: mencoder/mplayer is to noisy :-)
