I was over at my friends house and I had my harddrive in his 360. He doesn't have oblivion or Halo 2, which i had brought with me, he also doesn't have xbox live yet. I put Oblivion in and noticed that the little message that indicates i have downloaded content didn't pop up. It also said that my current save file had dowloaded content in it, but the system couldn't find it. I also coulnd't play on any of the downloaded maps for halo 2. I went into my memory and confirmed that I did have each download. but i was able to play the demos i'd downloaded of xbox live. his xbox is new, mine was 2005, is my hardware too old for his or what?
