If you are installing codecs on your own you need to choose either your own codecs, or the Shark007 codecs. You are causing conflicts to install ffdshow, Haali or anything else along with the Shark007 codecs.
The Shark007 codecs cover all formats even RealMedia;
you do not need to install anything else.
I suggest you uninstall EVERYTHING codec related starting with the Shark007 codecs.
reboot your system
install only the Win7codecs and the x64 Components
Afterwards, In both settings applications, slecet the checkbox at the bottom for suggested settings
Remember - Shark007 uninstalls MUST be performed from the Help TAB of the Settings Applications.
