yes, I tried to use it on my 2010 TV. I could load the main page, but was not able to select the two bottom menu items.
So it did not work.
But the reactions from bong.tv were pretty reactive. Since they had problems with Samsung, where they created an app, but Samsung did not release it officially, they want to go the HbbTV portal way.
Let's hope, they will look at the problems ...
PS: I someone want to load it, please add a "/" at the end of the URL. Else you will see an ugly layout since CSS-Style are not loaded correctly.
