I made a HTML5 video which plays well in all modern browsers. However, it needs to successfully "fall back to Flash" in IE6,7,8.
When I look at my site in IETester with its emulation of IE6, IE7, and IE8, these browsers play they flash version of the video as they should.
In order to see if Flash is working in IETester at all, I go to http://helpx.adobe.com/flash-player.html which quickly displays that Flash is working, but then crashes, so I'm not really sure if IETester is showing me what users of these actual browsers see who have Flash installed.
How can I be certain that IE6, IE7, and IE8 can successfully run the Flash version of my video without installing these browsers and flash on other machines?
