Xbox 360, latest dash, no aftermarket firmware. bare bones stock.. recently, when i put anything but an Xbox 360 game inside of this bad boy it will work great, but as soon as i put a 360 game in it, it will read the disc and then just say "Play DVD". which will then take me to a screen telling me to put this xbox 360 game inside of an xbox 360 to play it. if i am bored enough to repeatedly open and close this drive for 5-10 mins, it will finally read a game.. any game. anything i can do to fix this bastard?
