<!-- This sample demonstrates a way to subtitle a video. A RealText clip 
with a transparent background overlays the video clip. The RealNetworks 
extensions namespace must be declared for RealText transparency to work. -->

		gives the RealText clip a semi-transparent background. Using "0%" for the opacity value would
		render the RealText background entirely transparent. The "45%" value helps to make the 
		text more visible, while still keeping the video area beneath the text visible. -->
