I'm trying to burn a DVD .iso image. A few minutes in the burn, the estimated time jumps to 2 hours. The burn completes, but it ends up taking the estimated 2 hours and my CPU runs at 100% The image is for a backed up Wii title, the burn completes and loads, but is corrupted and gives disk read errors at certain points in the game. I've tried a few different burns at different speeds, but the results are the same. Any ideas?
