I am using DVD Shrink 184.108.40.206, Nero 220.127.116.11 and a Plextor 708A. I backup many DVD's without problem and then it just started making coasters. It burns 1 or 2 correctly and then it will burn 1-2 bad ones. So it is not every burn. I have updated the Plextor to the latest drivers. I am using DVD+R and DVD-R's and both give bad burns half the time. When I burn using the DVD Shrink (using Nero) it gives me an error of "Plextor read error" at the very end of the burn. When I burn by opening up Nero itself then it gives me a read error at the 98-99%. I have updated the Plextor to the latest drivers. I think it may sound like the Plextor drive being the problem. Any ideas of what could be wrong? Has anyone had any problems with any of these programs or could it be a conflict with one or all of them? I am really getting frustrated at making so many coasters. Thanks for your help.
