FinalBlast, I do rendered videos to. If you still have the 3D file and can rerender it then you can do it, otherwise you won't be able to do it well. Just place two cameras at the same point, rotate them on the opposite directions on the "up" axis (in Blender it's z) about 5 degrees and move them apart along their flat plane (if the rotation is z then use the x axis) the same distance in opposite direction until they both point to the exact same location. Now that's a very simplistic way to do it, but it should work.
I am still having a hard time getting my Flash plugin to respond correctly, I think I need a full systems reboot to get it though, running Ubuntu and currently rendering a large video.
