Depends on what you are trying to do. I will assume you want CoreAVC to decode video while FFD decodes AAC audio.
Open MPC-HC > options > internal filters
uncheck MP4/MOV under Source Filters (also Matroska if you want Haali to be used for mkv files)
uncheck AAC under Transform Filters click apply then ok.
Go to All Programs > Haali Media Splitter > Haali Media Splitter Settings > Options > Output
Click on "Use Custom Media Type for H.264" and set the value to NO
Go to All Programs > FFDShow > audio decoder configuration
click on codecs and set libavcodec for AAC then click apply and ok
That should do it.
Would it be better to use Haali that comes with CoreAVC? In which order do I install the programs?--
