Anybody else getting a disk read error while playing Reach? Ever since the matchmaking playlists got updated I've been getting kicked to the dashboard after playing a handful of matches...and I've had Reach installed to my harddrive since day 1.  
 
Apparently this has been going on since release and I'm just late to this shitty party (as seen at Bungie's message board and some coverage by G4 and Gamespot).  Hope this gets fixed with another update... 
   
Thoughts? I'm not the only one, right?

I think folks were saying you need to delete it off your hard drive and reinstall.  What I'd do in your position is delete the installation and try playing the game with just the disc and no installation.  If the problem persists it might be a more serious bug.  If it does not, try reinstalling it back onto your drive, sometimes a corrupt file just needs to be reset.
