In another move against pirates worldwide, Sony unveiled and attempted to adopt "BD+", a type of virtual-machine encryption that allows a Blu-ray disk to determine if the player is hacked. Unfortunately, the earliest adoptions of BD+ show abysmal results. Fantastic 4: Rise of the Silver Surfer and The Day After Tomorrow are the first two movies to feature BD+ encryption, and neither of them will play on Samsung's BDP-1200 and LG's BH100. While both companies promise to release firmware upgrades within the coming weeks, there is a bigger problem: disks with BD+ loaded on them take up to two minutes longer to load than their encryption-free brethren. And even when the disk does play, there's a good chance that it will either crash or stutter during playback.
