Tobias,

Some more testing and Richard's help were enough :)

Read it here: http://article.gmane.org/gmane.comp.video.mplayer.user/27180

Basically my problem was that by using the denoiser in the -include file 
and softpulldown in the command line the denoiser was loading first. 
Lesson learned :)

Thanks anyway.
