It seems like SG-1 is trying to set a record for show with the DVD sets with the most factory defects ever. I've heard loads of horror stories about people who couldn't get disc 5 on their Season 7 set to work. I also have friends who keep running into problems, first with disc 3 on Season 4, then on disc 5 on Season 9. And I keep hearing about other people that suffer similar problems. What's the deal?
