Regarding the Stargate-Atlantis Season 1 box set DVD where disk 5 contained same contents as disk 1: Amazon was very helpful and very prompt with helping me out with this problem. All I did was send an email regarding the problem to customer service the day I discovered the defect. The very next day, a new set was shipped to me at no cost to me. Within 48 hrs, I had my new set and disk 5 in the new set was okay. I shipped back the original set at no charge to me since Amazon's own shipping label is printable online. Thank you Amazon for handling this issue so well! I am very pleased! Nobody should hesitate to buy this product now because the issue has been resolved. I think in my first review, I blamed MGM for the error. Sorry about that! MGM products are generally 1'st rate. When I read that it was Sony that goofed, well, I wasn't surprised. But, all's well the ends well. The Atlantis series is a must have and the box set is very nicely done. I only have one wish with regards to box-sets and that is to have all multi-episode stories presented as one long movie without credits and theme music repeated at each end of each segment. I know, they are presented as they were aired, but frankly I find it very interruptive to have to scan through menus and credits and "previously on Atlantis" scenes in the middle of a great story. Maybe there could be a "play all" option in the menu that that applies to multi-episode stories that would automatically and seemlessly jump from the end of one episode to the real beginning of the next.
