Thanks for the article, I wasn't able to watch this free video though because of geographical reasons.
However, I found this: http://membership.cyberlink.com/support/product-faq-content.do?id=4359&prodId=1&prodVerId=-1
I ran the tests and it seems that my display is not HDCP compliant.
There's got be an issue somewhere in PTV3000 or WiDi, because when I connect laptop with HDMI to the display everything is fine, so the display & cable are good.
I get the same result independently from duplication mode.
The message I get from VOD sites is something like "Your computer doesn't fulfill all requirements needed for playing DRM protected videos". It's in Polish (from ipla.tv) and probably is written by an engineer to handle an exception coming from SilverLight...
This HDCP checker from the link above, complaints also about the drivers version for graphics card in my system.
My laptop contains Intel HD Graphics 3000 with 9.17.10.3347 drivers, which seems to be the latest (downloaded from Download Center).
