We are working to resolve this as quickly as possible.
Technical Issues with this Product
The manufacturer has confirmed the following technical issues with this product. The sound has been incorrectly mapped on some episodes of Star Trek: The Next Generation - Season One
on Blu-ray. This error will impact customers using a 7.1 or 5.1 Surround Sound environment. Until corrected discs are available, we have removed the product from sale. We are working to resolve this and will be contacting customers who have previously purchased this title from Amazon.co.uk.
So I guess this means Amazon will be contacting those of us who got it from them soon.
