ihave made backups of my games they work perfectly on my xbox but they wont play on other xboxes can anyone help
First of all, your xbox is modded. Other xboxes may not be. They HAVE to be modded in some sort of way before you can play backups. Secondly, the different xboxes accept different media. There are four known xbox dvd rom drives, and they may or may not accept the media you throw at it.
