I'm owner of Nvidia Shield and a Avermedia live gamer HD so i've trying to do something to capture stuff with a mini-hdmi cable but i got an error about the Shield is HDCP restricted.
I Mean : Everywhere: dashboard, emulator, games, ...
There isn't a lot of discussion about that but somes (here) say there is not hdpc ... i'm here to warn you about that.
I just buy a hdmi active splitter who normally bypass this protection, i'll keep you informed.
--> If you have any suggestion for desactivate this protection directly inside android it can help (it's cheaper... )
Have a nice day
