I'd like to have something good for 3D rendering (ala Matrox Impression) too, if possible, and I had thought up to now that I'd have to have 2 cards - the Impression and this Diamond board (or something else). If the Comet/Marvel can do BOTH, then my checkbook is ready and waiting - money no object! :-) > MPEG hardware initially.

That's essentially all I want anyway. In fact, if I can get this combo to work then you guys may very well have a _very_ strategic partnership come out of it. I'm not saying any more, except that I'm playing "point man" for a much larger (and richer) concern on this at the moment and am interested in any and all solutions. Maybe you and I should have another telephone conversation soon! :) > while there was a live video window.

Of course, by the That's also an acceptable constraint, at least for now. We just need to figure out a solution that will allow us to: 1. Show scalable video in a window. 2. Animate 3D objects at high speed using Reality Labs(tm) or something similar. If you've any suggestions, like I said, I'm more than willing to invest in a research platform. I've sort of backed off for the moment out of confusion over all the different video boards available! :-) Jordan
