Im bout to take my Xbox to a place that installs Enigmah modchips. He says hes not sure if it plays backups (dvd-rs). I just want to make sure this is the same Enigmah chip that i see online that confirms that it plays DVD-Rs, and that im not getting a different Enigmah chip that only plays imported DVDs. So will this Enigmah chip definently play DVD-Rs? thats all i really care about.

All Enigmah chips will play DVDR backups. However if it is a beta chip some games may require a patch.

Here is a link that shows pictures of the chips so that you can tell which chip you are getting.
