Yeah I agree that the StreamTheater isn't ideal at the moment. In the end I've used a different setup following this really well done tutorial -

Keep in mind that the FreePie is part of your download for OpenTrack and the version included in there is working great. I hope this helps to some while the Theater is broken, but in the mean time I'm surely having fun. When the CV1 is locally available and ED supports it I will surely give it a try, but for now it is much better experience then my projector.
You will need the app disabler for this to make sure that you don't get occulus apps when you plug into you Gear VR. I've used Package Disabler Pro and it works just fine
