I can play video from Youtube, but when I put the embedded code on my web site, it shows to my computer a blank black box image holder. On my other computer it shows fine, on my friends computer it's fine, but mine....some setting is preventing it from rendering. Also, it's not just the embedded video code, some other sites (see my original post for links) it doesn't show either. Plus some images, still and animations aren't playing.
See what I'm seeing and what I should be seeing in the above link ^^^^^^^^
