Lets not forget that the 360 uses/has used many different brands of DVD-drives, from Ben-Q to LG and others. I'm actually surprised this is the first time problems like this has arisen. The Wii has also seen an occasional issue with certain consoles but there it has to due with Dual-layer DVD finicky drives. I'm gonna go out on a limb and guess Sony uses Sony BD drives which is why we haven't heard of trouble there. Even then I'm sure there is some difference in model year to year.

who cares??? they already made their money. Its probably a very small amount, but MS did say that about RROD when it first happened

Well pot tweaking does indeed get lasers working again usually, the downside is you shorten the lifespan, then again if its dead whats to lose I guess lol.

if its a faulty dvd drive. how come its just for this one game.

Because not all the dvd discs are the same. DVD burning softwares, like Nero, can do quality tests on dvd discs (not drivers, discs).

I'm sure you would care if it happened to you. It's not about money here but customers.

I had this happen in 2008 and 2010.  It's an Xbox problem, not a Reach problem.

I played the entire campaign without a hitch, I've actually been hearing it's because a lot of older Xboxs have dust around the CD drive making it hard to read all the data on games with a lot of content.

^^^You're probably right.  Fable 2 and Mass Effect 2 had issues for me, in the past. 

best looking halo ever is reach and now this?
