I just got Family guy and my set had two dics three's!!! Just wondering if anyone else has had this happen before? Mine had all the discs but on the spindle that disc three goes on there were two of them!!

Not with a movie, but I've had it happen with videogames before. Like when I bought Shemue and it had two Disc 2's.

never had that happen, but I have purchased a couple of DVDs that were missing discs

I've had that happen with CD's quite a bit (~5X). I own a copy of Entrapment DVD given to me by a friend who had two in his set.

I actually had (2) Disc 3's in my Brazil:CC last year. Everything else was there, so I guess it was a bonus to have a 4 Disc set as apposed to a 3 Disc set.
