ace: No.. If you have a media center PC, the xbox360 simply streams the content the PC is outputting.. If you install a browser (not by default) on the media center pc, into the Media center interface, you can access it by the xbox360.., since it streams the media center output from the pc.

Its pretty annoying it streams the things, since it makes it slower, to f.eks. stream the thumbnails of directories with videos and such :/
