I am trying to copy a DVD onto a DVD-R. I have the DVD Decryptor and DVD shrink. I also have the Nero software. I've tried to copy but it doesn't work. I already ran the dvd using the DVD decryptor and saved the files. Then i opened them in Nero and tried burning onto the DVD-R and it says it has successfully been written, but the DVD-R doesn't work.xWhat do I need to do to successfully copy my movie?
