I went online at xbox.com and was reading about backwards compatibility, so I popped in Halo 2 and nothing. I tried COD3 still nothing. I followed the directions and signed up on Live the 360 updated, but I still have no luck using any original disk. I have a ton of these games and figured this is supposed to work correct? I will keep trying others but I must be missing a step or something.

Thanks!

you have to run a backwards compatability update on the console. if you go on xbox.support it will guide you from there. It willl also give you a list on what games you will be able to play.
