Layout alignment for playing multiple FLV files

ActionScript 3.0 FLVPlayback has an align property that specifies whether the FLV file should be centered when it is resized or positioned at the top, bottom, left, or right of the component. In addition to the component's x, y, width, and height properties, the ActionScript 3.0 component also has registrationX, registrationY, registrationWidth, and registrationHeight properties. Initially, these match the x, y, width, and height properties. When loading subsequent FLV files, automatic re-layout does not change these so the new FLV file can be centered in the same place. If scaleMode = VideoScaleMode.MAINTAIN_ASPECT_RATIO, subsequent FLV files can be fit into the component's original dimensions rather than causing the component's width and height to be altered.
