I found it… not sure how I missed it the first time, but GMail has it in this thread.  Sorry.

In FX, the rendering model is completely different, and FX doesn't use heavyweight components (Panel, Canvas), so the only rendering surface we can expose is the window itself.

Canvas is sort of close to what is needed, but it fails completely for my use case and simply crashes the app because it runs out of memory.  The FX Thread doesn't service the changes to the canvas fast enough for me to paint live video into the canvas.  If there was some more direct way to paint into an image's backing store, that might work.  Or even some special Canvas/Image that gave me access to a native graphics context (OpenGL texture or DirectDraw surface for example).  I've also asked for access to a mechanism to provide my own raw image data to the media APIs, so it could somehow fit in to the existing video playback support.
