basically all "stealthed" means is making sure your game .iso has the proper "security sectors" present. I use a program called xdvdmullter to check all games that are going to be played on my xbox. http://forums.afterdawn.com/thread_view.cfm/476770 this allows me to see before hand if the game is properly "stealthed" before I stick it in my xbox and test it on xbox live. I've heard of people who didn't have the proper security sectors present on their burnt game and have payed the price of being "uncovered". I'm not the most computer/tech savvy person in the world so I'm slowly learning more and more about how all this works.
