Regarding Crakle - I am able to play it both on laptop and WiDi - so for now the issue is only reproducible on SilverLight...
If it relates to media player software - I am kind of sticked to SilverLight as it's used by VOD sites that I'm using. There is the same behavior in at least three browsers, including IE.
Intel® Chipset (INF) and Intel® Management Engine drivers relates to motherboard of a computer and I should download them from intel.com right?
