3 options:
1. Flash your dvd drive. This allows it to play burned games. Easy to do if you got the equipment.
2. RGH your console. This very hard to do, and requires you to dump your nand (soldering) and glitch you console with a coolrunner, wich is more soldering. If you know how to solder then RGH is cool, since it allows many cool stuff, like custom dashboards, and playing games directly from hard drive with no disc in. RGH is not possible on xbox live, and will get you banned after 10 seconds.
3. Get a xk3y. This allows you to play games directly from a hard drive, and is also live safe. This requires you to get a dump from your dvd drive.
