xbox causes scratches to your disks it well reported(still they now just released in uk same problems r still there)
microsofts answer is they r very slight dont appear to affect playback they plan to do nothing nothing
so question is who is going to throw there money at bill when hes selling something thats scratches your origanals
most us here have chips to protect our origanals
sorry he not getting my money till i can make backups of my origanals keep the origanals in good nick
lets see bill say there no need to make backups
