Hi people, i brought a copy of Half life 2 off another memeber of this forum who said he was selling it because it was not compatible with his Tv. However i got the game today and it does not work! I put it in, my 360 goes to read it and then stops, and open tray comes up instead of the usual play game. Now before you say it, iv tested other Xbox games, and Half Life 2 is on the list, and iv just updated the software with the CD, so waht on earths going on??
