OK, that makes sense.

OK, I was able to get that to work, too.

Well, apparently there is a problem with javascript + WebViewMBS when using the
<audio> and <video> tags of HTML5. I can't get any of the following working for
those tags:
document.getElementsByTagName
document.getElementById
document.getElementByName
There are many scripts online including Apple's own script, which uses these
get methods and which work in Safari:
<http://developer.apple.com/library/safari/#documentation/AudioVideo/Conceptual/Using_HTML5_Audio_Video/ControllingMediaWithJavaScript/ControllingMediaWithJavaScript.html>
but the javascript sent to WebViewMBS doesn't return the object.
Thanks,
Aaron
