Adjust a web page's code to display HTML5 video w/Flash video backup

I'm having a difficult time with some coding on a web page for my clients. They want the video to be hosted on their site (which it presently is) and they want to make sure it displays properly in IE 7 and up, as well as all other major browsers plus iPhone/iPod/iPad browsers. Here is the page: [login to view URL] My solution was to use Video JS to display the HTML 5 video in the form of an MPEG 4 video (which is already hosted and in place). When a browser views the page that is incompatible with HTML 5, it will default back to the Flash version of the file as a .flv (also, already hosted and in place). I am using Flowplayer for the flash video playback. Video JS has a provision for this type of functionality but I am unable to get it to work. I need someone who has done this type of work before and who can make the adjustment I need so that the video displays in the manner I described above. I've gotten it to the point where the video displays correctly in most browsers, excepting Internet Explorer 7 and 8. I need someone to make the page work on these two browsers while also retaining the functionality on the other browsers.
