Sorry for newbie question, but I'm new to Blu-ray. Does Nero remove protections or do we still need AnyDVD HD running while Nero is copying? PS. It seems most people on this forum play the Blu-ray movies from a hard drive instead of a backup Blu-ray disk, why is this done? If very many Blu-ray movies are collected, ripping to a hard drive would take a huge amount of disk space.
