I am having problems making sense of this, so hopefully someone can help. I let my kids play with thier own DVDs, so I make backups and let them use them. That way if they get full of penut butter and get all scratched, I'll just make another copy. To make a long story short, a few originals got trashed, but I did have most of the backups. I was trying to burn about 6 of them, and the first 1 went through, the second and third failed, the forth worked, and the 5th and 6th failed. I am using DVD Decrypter and the media of the backup is TDK. The drive that I used to burn them on broke and I now have a new one. The old drive was a -r and the new drive is a +r. Now this is what seems strange. The ones that passed are on TDK 2X disks (-r), the ones that failed are on TDK 4X disks (-r). The firmware on the drive is up to date, the disks are clean and work well in the player. Can there be a connection between the 2x disks copy, but the 4x disks won't? I get either a No seek error or multiple read errors. On one disk using DVD shrink, it can't even see the movie, only the DVD X Copy screen, yet the movie plays on the DVD player and the PC. Go figure.
