Sony announced at this year's Consumer Electronics Show that future Blu-ray titles will contain a portable copy of the movie/show embedded on the disc encoded specifically for the PlayStation Portable.
Consumers will able to boot up their PlayStation 3, pop in a Blu-ray disc, then simply copy the portable version of the disc to their PS3. From there, PSP owners can transfer the portable copy over to their handheld device.
It's good to see that movie studios are finding ways to take advantage of the extra storage space on Blu-ray discs. Hopefully we'll see this feature adopted by many new BD titles in the near future.
