What are the must-know tips & tricks for my Xbox 360? I'm still figuring out the basics: downloading add-ons and deleting old stuff; switching between DVD games and downloaded content; connecting controllers to the device I haven't yet learned how to buy points to buy content. I still don't quite get the "blades" or the online system. I have no idea yet how to create a custom icon for my Live ID. I don't need a walkthrough, but I'm curious what people think are key tips or must-try things with my Xbox.
