Do you have an apps folder on your hard drive? If so, create a xbmc folder in the apps folder and place xbmc inside of the xbmc folder. In the avalaunch.xml file find the entry about xbmc and specify the path to xbmc. You need to create a folder called movies or videos or anything you want and put you movies there. You will have to edit the xboxmediacenter.xml file to specify your movies folder. Well you don't have to do this but it will save you time in the long run. Let me know if you need to know anything else.
