Yes- see my earlier post about Warner HD-DVDs. I have ALL of their titles (except Twister which has been hard to find at a decent price), all bought still sealed but I wasn't able to watch many of them for more than a year afterwards. When I finally did, I found that many would freeze up in the middle or not load at all. When I posted about it some people checked discs they had bought a while ago which had worked fine and had trouble with them too, suggesting they're getting "laser rot", deteriorating after being manufactured (a problem that's been around since the first laserdiscs.)
Since I'm an obsessive collector I've persistently been re-buying more sealed copies (at my expense) and think I have most of the bad ones replaced now- last one I replaced was Season 6 of Smallville which had bad disc #4s in multiple sets, and now trying to get a working copy of Cream at Royal Albert Hall put out by Rhino but manufactured by Cinram.
When I first discovered this large number of bad discs I contacted Warner's customer service who told me they would replace them with Blu-Ray discs ONLY if I had the original receipts, and only if they were from 'authorized retailers' and not Ebay or Amazon resellers, even though they were obtained brand-new. Once I have a good copy of the Cream disc and have verified that all my Smallville discs are working, I plan on sending all the bad discs in a box to Warner Home Video's president with a nice letter and maybe a printout of threads like this one, and just say that I'll assume they will do the right thing.
