Yeah, I'm on 32bit vista, so I guess that explains the issue. It just seems like such a simple problem, yet I spent the better part of yesterday doing research and experimenting with different programs (autohotkey, sharpkeys, keytweak) and registry hacks, but I can't seem to get those buttons to do anything except launch quickplay. I don't understand how the PC can only be aware of the button press if Quickplay is installed. I would imagine it's a driver thing, like the buttons are treated as separate hardware that needs a driver which gets uninstalled with Quickplay? I wonder if it's possible to keep the driver and get rid of the app... One more day wasted? This would be so useful, though.
