Field of view wrong

I'm using the OvrCameraRig and I have a movie running on a skybox. I would like to adjust the y value on the camera so that the camera is closer to the floor. 

1. How do I lower the camera?

I have also tried to change the field of view but it seems impossible on the quest. The world appears a bit too small and I feel like a giant in the vr-world. I would like to scale the world up a bit. I have tried to adjust the FOV on the Left-RightEyeAnchor, CenterEyeAnchor and on the Main Camera in the scene but nothing has any effect on the percieved world scale.

2. How do I change the field of view

Thanks alot
