I was tying to backup GTA IV on PS3 on my LG GGW H20L Blu-ray writer, but when I insert the disc in2 the drive nothing happens, says no disc in the drive. I have already played and made backups of Blu-Ray movies but not PS3 games. Is this normal, they cannot be read? If so why? They the PS3 game is ablu-ray data dsc is it not? So why can it not be read?
