Right now, you CAN watch movies while lying down.
Please follow the steps below:
- Press A/X/Trigger button to call out the control panel
- Click Cinema Scene on the upper-right corner of the control panel
- Select Void, Space Station or Moon scene
- Hold on the screen to drag it to the desired position while you're lying down.
Also, you can browse the video list while lying down. Just call out the control panel and tap "Video List".
To make the screen follow your head's position and orientation, please simply press Advanced Setting on the control panel > Screen Adjust > Lock Screen, then your screen will track your head position and orientation.
Hope this helps.
