Got it worked.
I changed the region of my PC from France to English US and i do not have error message when i launch amarectv. Nice

Then i replaced the HDMI-DVI cable by a regular HDMI cable and i manage to get signal and video displaying on my computer.
That's nice.
However the picture is way too big. it is like to picture is zoomed.
I cannot get the full screen i do see half of the picture!!

I set SA7160 PCI analog 01 capture in graph 1 and w720 h240 59.64....
Same thing in live section.
I have also problems getting sound signal.
I have got a Creative X-Fi Titanium HD sound card.
Hope i will solve both issues.
