I sort of had the same thing happen to me. I pre-ordered the set in June before the delay. Once the new release date arrived, my order was still sitting there in 'waiting to be shipped' mode but was promised to arrive on the release date. Didn't happen. I had to call Amazon and they cancelled...
I did double check each episode and those are the correct running times. I'd get a replacement set if I were you. It does sound like you got a bad set.
