This allowed me to build pix_videoDS with the 'latest and greatest' SDKs. You would think a $50 billion a year company might, you know, document these things, but I guess not. Only two days spent tracking this down.

On to the next layer of hell - making it actually work and run well.

I built the DirectShow Sample stuff (which is now no longer part of DirectX SDK?!?) and I'm using VS Pro 2003 which is quite painful.

Any clues?
