Does anybody know why some DVD`s can be copied to Harddisk (I am running DVD`s on my PC with the Sigma DVD Station) and others not. Often, rented DVD`s can not be copied, a message appers saying "Device does not accept copy command". This happends while copying the the Win Explorer, also other copy-programms show a similar message. Copying a DVD is not illegal if done for private use. I would appreciate any help.
