bsplayer and remote control

[lew]

I have assigned different keys and commands,for my bsplayer when it is open;I am very happy about. But first, always i have to point at my hdtvpc
with the mouse of my remote control (in fact a 4 arrows mouse),and it is very difficult to open bsplayer(that means moving cursor over the tv screen).My remote control is a Shuttle pn 31 and has automatically assigned a launch button for windows media player that i never use.How it is possible to reassign that key for launching bsplayer or at least how to assign a button to open bsplayer after I open my pc (to close bsplayer it is possible).
Please help me !!! I am not a programmer but I can change some registry keys if it is necessary
