Thanks, I will get some new disks. However, I have successfully burned 10 backup copies of another DVD using Nero, Copy DVD. Doubt that uses ISO files though. One last question before I go buy some new DVDs. Have you seen a case where the ISO file produced by DVD Shrink doesn't burn?

I used DVD Shrink 3.2 to generate my ISO file, then using IMGBURN 2.0.0.0 tried to burn the image. The original came from a +R DL disk with 6,721,404,928 bytes. The compression settings were on Automatic. I used Write, not Build with ImgBurn The write completed successfully, and then the tray cycled to begin the verify and the device never recognized the DVD - Device Not Ready (Medium Not Present) See the following log.

Okay, I noticed the size of my source file was very large, so then I went back to DVD Shrink and recreated a new ISO file using a custom compression ratio of approximately 70%. This took much longer to create the ISO file of course. However, the result was the same, as you can see in the log. I 10:50:54 ImgBurn Version 2.0.0.0 started!
