Only other thing I did was remove the option to hide Live TV on the home screen. The user has to explicitly enable it anyway, so I'm not sure why anyone would turn it on and then proceed to hide it. If there's a good reason for this, just let me know.

I haven't tested what occurs when you are trying to access the Live TV settings if you haven't a PVR version of XBMC. I have added the option for this reason.
The main menu entry can be easily hidden but I haven't found any system variable to know if the XBMC version supports Live TV or not.

If I don't select Settings->Metropolis->General->Enable Live TV support then I don't see the settings icon for it at all. Nor do I see the item on the home screen. If I do enable it, I see both of these, albeit with empty strings.

This seems like correct behavior to me. Am I missing something?
