Postez aici. Pare ca problema ar fi fost o fabrica din Pennsylvania, dar nu e clar daca servea doar piata US:
- Hundreds of your Warner Bros DVDs probably don't work anymore; UPDATED with response from WB
Warner Bros. Home Entertainment is aware of potential issues affecting select DVD titles manufactured between 2006 – 2008, and the company has been actively working with consumers to replace defective discs.

Where possible, the defective discs have been replaced with the same title. However, as some of the affected titles are no longer in print or the rights have expired, consumers have been offered an exchange for a title of like-value.

Consumers with affected product can contact the customer support team at [email protected].

Also, nu stiam ca life expectancy al unui DVD e 30-100 ani, conform Sony:
A typical DVD disc has an estimated life expectancy of anywhere from 30 to 100 years when properly stored and handled. How the disc is stored and handled will determine the longevity of the media.
Overall, reminder sa faceti backup la physical media.
