If anyone is reading this, I've discovered in "Security Options" that I have "Secure GC enabled" on this device. I don't know if this is relevant to the OS problem I'm having. There's no apparent way to turn it off.

I checked here, View Document and it says that "Secure GC enabled" means that I have content protection turned on, but in fact I don't have it turned on.

Can anyone shed any light on any of this?
