Fix to my workaround. Exploring all the fonction available using XP with gbpvr.exe running as shell, i noticed that my previous workaround was only working partially. All navigation fonction are ok, but sound commands (Vol up, vol down, and mute) were not working any more. So it installed a little tool (nircmd) and changed my default section into irremote.ini to Sound control is now available again
Enjoy and let's hope there will not have any more surprise like this
Code:
MUTE={run(c:\gbpvr\nircmd.exe mutesysvolume 2)}
VOLUP={run(c:\gbpvr\nircmd.exe changesysvolume 2000)}
VOLDOWN={run(c:\gbpvr\nircmd.exe changesysvolume -2000)}
Enjoy and let's hope there will not have any more surprise like this
