Im not certain about this but I know that XBMC has some very flexible hotkey options (ie by editing keyboard.xml) You might want to look into that to see if you can assign an unused button on your DVD remote to do something like temporarily stop xbmc? I haven't fiddled around with keyboard.xml a whole lot but its worth a shot I think. http://wiki.xbmc.org/index.php?title=Keymap.xml
