All of my dvds have been failing at 99% of the burn process. I am using dvdshrink and nero, DMA is on, firmware is updated. I just started using Memorex 8x DVD-R discs and it has done this to the first 6 discs I have used. Some of the movies play fine and some don't. I have been through a pack of verbatim DVD-R 8x without a coaster, then tried TDK 8x DVD-R pack and had a few coasters, now with the Memorex everyone that I have used has failed at 99%. I can post the error message if I need to. Any help would be greatly appreciated.
