Anyone know how can I use a blue screen technique with MPEG video or AVIs to either add a BMP or second AVI as a background to a foreground video? I guess I'm thinking of either as app OR a VB technique

There have to be some answers out theire somewhere:confused:
You'd have to go through pixel by pixel, but you'd still have to deal with anti-aliasing (partially blue pixels).
And there's always Direct3D. Try mapping 2 triangles with the AVI, and then making another 2 triangles, mapping them with a 32-bit image (with an alpha-channel). This will give you any transparency you'd like. Use the Direct3D surface maker that comes with the SDK. This is the only way that I can see you can do it with reasonable speed.
Or you can go with directdraw, and hope that the alpha-channels work.
