WMV Streaming of a DirectX render

Question

I've written a real-time visualisation app in DirectX. The thing is, it should be displayed on multiple computers, as a videostream.

I'm guessing WMV will be the easiest codec to do it in, since it's MS and all that.

So, how would I convert a series of DirectX screengrabs to a fluent 30fps WMV video stream?
