I think this is what you need

Hello. Originally posted by Berryone: Change the target size to 4300 mbReduce the burn speed from 16x to 8x or 4x.This fixed it. After DVDShrink scans the DVD and you click 'backup', you can change the burn speed settings. I changed it to the lowest setting and I was able to backup everything I had.Thanks for the help M8!!
