<p>How can I set the font used by the FLVPlaybackCaptioning component for subtitles?  Using the style property of the textarea does nothing, and using a TextFormat makes the text go blank, even though the font had been embedded.</p>

It seems the font, as well as the other properties of the text, are specified in the XML file where the subtitles are read (this is from the
documentation
):
```
```
<?xml version="1.0" encoding="UTF-8"?>
  <tt xml:lang="en" xmlns="http://www.w3.org/2006/04/ttaf1"  xmlns:tts="http://www.w3.org/2006/04/ttaf1#styling">
      <head>
          <styling>
              <style id="1" tts:textAlign="right"/>
              <style id="2" tts:color="transparent"/>
              <style id="3" style="2" tts:backgroundColor="white"/>
              <style id="4" style="2 3" tts:fontSize="20"/>
          </styling>
      </head>
      <body>
           <div xml:lang="en">
              <p begin="00:00:00.50" dur="500ms">Four score and twenty years ago</p>
              <p begin="00:00:02.50"><span tts:fontFamily="monospaceSansSerif,proportionalSerif,TheOther"tts:fontSize="+2">our forefathers</span> brought forth<br /> on this continent</p>
              <p begin="00:00:04.40" dur="10s" style="1">a <span tts:fontSize="12 px">new</span> <span tts:fontSize="300%">nation</span></p>
              <p begin="00:00:06.50" dur="3">conceived in <span tts:fontWeight="bold" tts:color="#ccc333">liberty</span> <span tts:color="#ccc333">and dedicated to</span> the proposition</p>
              <p begin="00:00:11.50" tts:textAlign="right">that <span tts:fontStyle="italic">all</span> men are created equal.</p>
     <p begin="15s" style="4">The end.</p>
          </div>    
      </body>
  </tt>
```
```
So maybe the component doesn't want you overriding those?
