I didn't have any success finding an answer or similar problem using the forum search, or dvd guides so I am posting my issue. I have flawlessly been using my Iomega dvd burner for +r/+rw backups since I got it several month's ago. I use dvdshrink and then nero for my backups. All of the sudden my drive will no longer read dvd's that I backup. If I backup a movie, and insert the the backup dvd in my drive, the drive won't read it. It was working fine up until a week ago. If I want to backup a movie I have to do it from the original again and play the backups in my regular home theater dvd player. I use tdk, phillips, and memorex blank media +r/+rw Although I have recently upgraded to the latest nero, I have made no other changes to my settings or how I do my backups.
