So, I was really excited when my package arrived yesterday, apparently without damage (I live in Brazil, so it travelled a long way).Today I decided to watch the first part of the 8-part documentary.I put the disc to play on my blu-ray disc player and..."Disc Error".I take it off, put it in again, and..."Disc Error".Starting to get nervous, I try the blu-ray disc of the first movie, and it works just fine.Looking at the recording side of the disc, I noticed that all the documentary discs (except for the last one)and the bonus disc didn't have anything marked, while the discs of the movies (the ones that worked, I mean) showed that characteristical coloured pattern when under the light.Apparently, the documentary discs came empty.I'll try to contact Warner Bros. and ask for a replacement.I really hope they solve this problem as quickly as possible.Sicerely,A disappointed fan
