Halo Reach Preview disk question

Hello! So I was part of the Xbox live dashboard preview before the update. I was wondering if anyone knew now that the update is out and the dashboard is live to the public, if it was safe to play my Halo Reach preview disk on a non preview registered console. Thank!

Thanks! Yeah it works. I was just scared because it says all over the disk not to use it on an un registered console and not to sell it so I was thinking if they didn't let it work on any other console but the one your registered it too then chances of it getting sold would be slim. I'm not oging to sell it because I never bought reach so cool!
