One of the chief copy protection mechanisms employed by Blu-ray discs that is unemployed by HD DVD is called ROM-Mark, which basically uses unique identifiers that can only be hard coded on discs by authorized duplicators -- in other words, it's that per-disc physical watermarking that makes copying (although not necessarily ripping) Blu-ray movies just that much harder, Which is partly why we're a little dubious about this new app, BRDGen, which claims to be able to make and edit (and export for recording) PlayStation 3 compliant disc images. Anyone with a Blu-ray recorder, PS3, and a healthy bit of patience care to see what this thing is capable of?
