Query: First two discs don't work!

I was very excited to see this disc set on sale for a pretty low price. When I got the discs, though, the first two discs were defective, not properly loading episodes from the menu. I explained the issue to Amazon and they were good enough to replace the discs, but the replacements had the same issue! I've seen this problem with the 30 for 30 Blu Ray reported elsewhere, so I'm surprised that nobody has posted about this problem here. I've notified Amazon and now they're looking into it.
