But that is what you need to do. Unless you are using your own player, you need to mix the 2 video streams, which implies decoding them, and rencode the mixed output. If you use your own player, you can mux (mux, not mix) the precompressed streams into a single WMV with 2 video streams and then, during playback, you can simply render the 2 streams where you want them to appear on the screen.
