I just started backing up my games for xbox, but have already had a few problems. I am using Memorex 4x -r's and they are not working well on my version 1.0 xbox with the Thompson drive. It takes minutes to load up the disc and it always ends up freezing right away anyways. I have tried burning two games, Max Payne 2 and NHL 2k5 and have gotten the same crappy results with both. What media should I use for my xbox games? Preferably something I can buy at Walmart, like Maxell or Verbatim maybe? Any suggestions??
