Good Day, I have a similar problem like anothe thread that I read but no replies were posted yet. I used to make backups with a LG 4120b burner, now I use Pioneer 108. I always used Ritek Ridata DVD-R Media. Now That I use my Pioneer to backup some DVD's I already backed up with my LG Burner, when it's time to do ISO READ with DVD Decrypter I get the following error: Incompatible Medium Installed. What does it mean ? It does not do it with all my DVD that I backed up with my LG but with some. Regards, Dan
