noob question here...

if i want to play a backup of a game on xbc and that game auto connects to xbox live when the xbox is connected to the internet how to i avoid getting banned?

turn your chip off, and if you cant do that then dont sign in on XBL, just go straight to system link

one way to make sure you dont get signed on is to transfer your live account to a memory card and not have it on your xbox. that way you wont be able to sign in to live

I wasn't aware of any games that did this, but like those above you said, remove the XBL acct from the xbox and put it on a mem card, you'll be able to sign in when you want to, and have no worries about logging in accidently
