I asked this on AVS and nary a reply, not sure if it's not possible or if scripting is a bit advanced for American HTPC owners. Is there a way to set FFDSHOW's parameters from a script prior to running? For instance, with some DVDs Denoise is a great tool and it'd be nice to be able to set that option when playing a DVD that needs it. I've hunted in the registry and can old find what appear to be large blocks of binary data keyed with 'FFDSHOW', which clearly needs deep internal knowledge of FFDSHOW to be able to change. If I have to I'll grab the source code and got trawling, but it'd be nice to avoid wasting my time if someone else already knows.
