Tom When I was doing active development with Direct Show. I think there was a way with the Direct X SDK developer tools to log and capture filter graph build attempts. If you can find both the ingress and egress points (Source, and Output) If you are determined enough you should be able to fill in the gap unless they were custom written filters.
