I have a new external Sony Drx-710ul double layer dvd rewriter. I have downloaded the nero software that it came with along with the dvd decryper and dvd shrink. I have no idea on how to make backup copies of the files larger than the 4.36GB. I have tried to shrink first then decrypt and vice versa. The files from the decrypter aren't recognized by the shrink and vice versa. And I just can't figure out how to get nero to work. Need to know which nero application I need to use (ie...express, burning rom, vision express, or back it up...) Also I need to know if the nero version provided by Sony has full capibilites. I really need idiot proof instructions.
