Impossible to capture from DirectX/OpenGL

[mrmister]

Hello
I am trying to capture from DirectX/OpenGL but I cannot... I see the button gray and I cannot press it.
I don't have that problem with the active screen button, then I see the red button to record from the screen.
If I press the gamepad button (to record from DirectX/OpenGL) then I cannot record anything, because the record button is gray...
How may I solve this?
Thanks

The button is always grayed out. In this particular mode you are starting your recording with F9.

I press F9 and has absolutely no effect, it doesn't record anything, I've search in the folder were allegedly should be the videos, but the folder is empty and the recording never start.
To be sure the F9 key is not being used by the game, I have selected other combibation of keys to start the recording Crtl + Shift + F9 and continue the same, don't record anything.
The game is X-Plane 10.
You can download a demo from here:

Perhaps you may download the demo and doing some tests... so you could find for what reason Mirilis is not detecting the game?
