I have a modded Xbox with a 200Gb hard drive all perfect and full of exquisite titles, all for my own enjoyment, although my brother continues to come by my place to take off with my Xbox. I recently read about the new Xbox Media Center Edition 2005 OS for the Xbox and the Extender and wanted to know if this would be easily added into my applications list without formatting my drive, hence losing all my "illustrious wonders". I love the look of the new OS and would love to add it to my setup.
