Put the hotkey on a different key (I use numlock) and the menu works.
It seems that the Video player feature is a bit hit/miss when it works (even when trying the same file). When it doesn’t work: DK2 stays off, amber light, webcam light does turn on.
I noticed that it usually doesn’t work after opening a video, quickly after another video was closed. Restarting Vorpx (Quit option in tray) usually seems to fix it.
Windows 10 64 bit
NVidia 780 GTX (Not at home atm so can’t see the driver version)
Oculus runtime 0.7
VLC Player (latest version), I’ve applied the tweaks in the Vorpx control panel
PS, When it does work: It is amazing! Already watched a few 3d movies with Vorpx :)
