I have used dvd dual layer (verbatim) twice, quite a while ago and very successfully with dvd decrypter (iso read and then write). Thereafter every attempt fails and cost a lot of money.
Can somebody perhaps (and please) explain the details on how to do it right.
I have: DVD Decrypter, Imgburn, DvdFab Gold, Nero and a LG 4163B dvd writer (rom). Work on Windows XP
Looking forward hearing from you
