Microsoft has finally got off their lazy asses and fixed the Xbox DRM issue.
What is this issue exactly?
The DRM issue is where you get a new Xbox 360 and you add your old hardrive to the console and you find out that none of your Xbox Live Arcade games and other downloadable content from the Marketplace are on your new Xbox.
The reason is these files were attached to your old hard drive. Now though you can transfer these files by going to http://www.xbox.com/drm and following the instructions in this video. One important thing to remember is that you can only do this once every twelve months so if your Xbox red lights more than once a year like mine then your screwed till the twelve months is over.
