XBMC4Xbox

Hi guys.
My xbox keeps buffering when streaming ice films, [removed] etc.
Is there a advance settings xml file I can use on the xbox.
I just built a raspberry pi running openelec xbmc and it just works perfectly on the same network. Must admin I am extremely surprised how well the little pi works:-)
But I would like to get the xbox working.
Thx.
Any suggestions would be greatly appreciated.

the pi found i not whery nice on gui is the xbox1 with xbmc4xbox faster !
to the streaming Problems :
the have a newer network module as the xbox1 on board the bus speed is better newer Ramm newer Harddisk-Controller the Datarate is most better the pi have more Ram and most of the video codecs assening the pi not over the cpu the graficchip will do the work!
