Wow, this a huge, huge screw up on CBS's part. How can something like this get past quality control? Did anyone over at CBS bother to listen to the final product before it was released to mass production? A screw-up of this scale has the potential to negativity affect CBS's credibility with future TNG releases, not to mention sales.
Ya its a mess. If there is a recall or something this is going to cost CBS a fortune fixing this mess and getting the new sets to the people who bought season 1 already. I hope they dont cheap out on later seasons because of all the money they will have to spend to fix the poor QC on season 1. Its such a shame as they could have got some Trek fans to watch and listen to the discs and look for audio or other errors for free I am sure.
