If you are having problems with this game causing your xbox to freeze on startup, or with the disc spinning at high speed even though the game is installed to your HDD, there are solutions to these problems.....
To avoid freezing, simply sign out of Live before starting up the game. Sign back in on the 'press start' screen. This should prevent all freezing issues.
To start the game without the disc spinning, simply play some music(from a USB or from your HDD) before starting the game from the dashboard. This will prevent the disc from spinning.
The freezing issue seems to be tied into update data, so that should be fixed eventually with a new patch.
The disc spinning issue has something to do with some new disc formatting Microsoft is using. I've heard that this is expected to go away when they do the system update before the end of the year.
I hope this helps.
