dr no Thanks for your reply and your help. My english is very bad and sorry for this. - You have reason, but I will try to explain better what happened: 1)I had a file of a film in ISO format in my disk. That image ISO was obtained with the clone DVD. Afterwards, with your help and of the Premmings I tried with the Decrypter and the Imgburner burn a DVD DL. After many attempts the DVD DL was burned with the Pinnacle; 2)Afterwards I tried an experience - With the backup of the film in the DVD DL I tried with the Decryper obtain an image ISO for afterwards with the Shrink compress that image into a DVD of 4,7GB. Appeared then to such message that already I referred. 3)Will have other alternatives to the Decrypter? 4)I bought 25 DVD Verbatim in Ebay German. I am expecting for them. 5)I thank again to your patience and to your availability
