Film collectors recently discovered that potentially hundreds of Warner Bros. DVDs released between 2006 and 2008 have become unplayable due to laser rot. The company has promised to replace some affected titles, but others may become much harder to find through official channels.
Warner Bros. has confirmed the issue and advised customers with damaged discs to contact customer support. However, the company will only replace titles that are still in print. Unfortunately, many affected DVDs are either out of print or locked behind licensing restrictions.
