[s76x]

hi,
I have windows vista home premium 64 bit

I don't know how, but I have discover a ffdshow codec in my pc without have installed codec pack or other strange 3rd party player. I have installed only adobe premiere cs4.

the ffdshow codec is in this directory:

C:\Program Files (x86)\Common Files\Common Share\Filters\FFDShow

there isn't an uninstall on control panel>applications (installing - uninstalling)

there isn't a voice about ffdshow on start>programs from menu.

I have tried also to remove the ffdshow directory manually without success

how I can remove it? please anybody can help me?

You could try Filmerit which should let you uninstall the codec from the Registry.
