Some people just don't get that DRM doesn't work. While EMI is starting to offer their valuable content DRM free, studios that support Blu-ray are pushing Cryptography Research to complete BD+, in an attempt to secure their content. Of course it's too late for those movies already out in the wild, but future titles from Sony and Fox -- who knows who else -- will employ BD+ to further secure movies even when AACS can't help. BD+ allows the studio to add an additional layer of DRM, that can actually execute code on your device to prevent playback. As bad as it is, it's not as bad as it sounds, after the disc is removed, so is the BD+ code and none of your other discs are affected. BD+ can be harder to circumvent because it is more versatile and can adapt to hacks, but it also increases production times on discs by one to four weeks.
