I try to play some videos on my Facebook, but it can't. "No video with supported format or MIME type" appear. I have install Flash, Java, Silverlight, QuickTime Plugin and Windows Media Player Extension Add-On to solve this problem but it doesn't work.

Can you help me? Thanks before

Update:

I use this to check the problems http://ie.microsoft.com/testdrive/graphics/videoformatsupport/default.html

and, it said: Your browser cannot play H.264 high profile content with the HTML5 video element.

The video could not be loaded, either because the server or network failed or because the format is not supported.
