I am having a different problem with D2D, although when copying large files, ie lots of photographs I do get the restart problem, my problem is that D2D refuses to close any disc. I receive an error message pointing out the failure and sometimes the disc is corrupted. All attempts to correct this by buying new DVD writers, uninstalling and reinstalling, e mailing Roxio (no reply) have failed. It used to work in version 8, had other problems so bought 9. So far wasted time and money.
