I expect a disc replacement for the third DVD will be absolutely no problem in this case; for once it's a blessing it's DVD-only, as remastering and redoing one disc will be considerably cheaper for them than redoing a BD (which they have frequently said is impossible for them as things currently stand). While it's true they have a poor record of replacing faulty discs in the past, in this case the fault is so severe that it seems unlikely they'll be able to do that.
Still, what an embarrassing mess to have made, especially as they have a history of glitches which would have been nipped in the bud with a simple watch through the material before release already. I think returning your set on principle if you have one ordered to pressure them into being more thorough in checking their work is a good idea. Otherwise hopefully next week when they've investigated they'll be able to organise a direct disc swap for people who can't send theirs back.
