I'm trying not to duplicate problems, but this is something that I've been been battling for a while and none of the solutions I've come upon here helped my situation. I am in the process of moving my site over to an SSL certificate-enabled IIS 7 server from another IIS 7 server. I copied all files over, fixed the urls, made sure the proper MIME types were accepted (including .swf files).
Now, within IE8 (because it uses Flash, I assume), my videos are displaying a blank screen. All other HTML5 browsers, it works just fine. Is there some other reason on the server side that this issue is occuring?
