First off, I was wondering how to tell the difference between a "system update" and a "game update"? Reason I ask is I'm trying to play Cars 2 on my modded box but it says an update is required and I won't be able to play unless I apply the update. should I apply the update? My box is already banned from live so not worried about that. BTW, I believe I'm running LT1.1 if that makes any difference.
