well if the movie is on the hdd succesfully, and u have just installed xbmp, u may need to point it to where exactly ur movie is. this is done by editing the config.xml file in the xbmp directory. i know the default settings were incorrect for me. in the file, there r settings for 'My Videos', and a url location which basically u want to point to where u will b putting ur movies. in my case this was 'f:videos' but it could be something different for u. probably the best way to edit the file is to FTP to ur xbox, copy the file to the PC, edit in notepad or something similar, and the reupload to the xbox. dont forget to keep a backup of the original config file though in case u make a mistake. hope that helps.
