How to disable start iTunes from remote control?

Hello! I have mac mini with XBMC (KODI) and I satisfy my MAC, but it have useless application iTunes, that starts every time I press play button on my remote control. I can't disable this feature and even think about windows pc instead if mac because I need to stop it, and there is no information on the internet how to disable start iTunes from remote.

I know about button "forgot all remotes" in iTunes, but it's not active, so when I start playing movie in my XBMC(Kodi) on background start music from iTunes. All my perfect apple world with more than 10 devices start crashing because of stupid iTunes start ((((( I need apple remote not for iTunes, because iTunes is horrible player and I do not start use it not now, and never.
