New Sony DVD DRM breaks Sony DVD players

New Sony DVDs have been corrupted with a DRM system that renders them unplayable on many DVD players — including Sony players:

Reports are starting to pile up of unhappy encounters with a new copy-protection system that Sony is baking into commercial DVD release and which renders certain discs useless on older DVD players.Drm

Suspect titles include regular (not Blu-ray) releases of "Casino Royale,' "Stranger Than Fiction" and "The Holiday," all of which render nothing more than a brief title screen on certain DVD players (including some Sony models).

DRM snoops say it's the return of ARccOS, a somewhat discredited anti-copying system Sony toyed with a year ago. The technology was quickly subverted by makers of DVD-copying software, but is robust enough to flummox some DVD players made by RCA, Toshiba, Philips and others.


(Thanks, Nick!)

Sony says that it has
updated this DRM, but that presumably doesn't do you any good if you bought one of the discs with the un-updated DRMs on it

— Thanks, Victor!
