Thread:Extension talk:TimedMediaHandler/flash fallback doesn't work

Thanks for a writing a great extension. It is working perfectly for me in chrome, firefox, and for mobile devices. I cannot get the flash fallback to work, however. In IE9 I get the notification "For a better video playback experience we recommend an HTML5 video browser." and when I click play it tries to download the webm version of the file. I've made sure to enable transcoding to h264 which completed successfully. I've tried setting EmbedPlayer.DisableVideoTagSupport to true for debugging. This causes all browsers to behave similarly - ie trying to download the file. Is there a setting I'm missing to enable the flash fallback player?
