This worked for me. I did not have any issues with Version 9.
1. Create your project in MyDVD with multiple titles.
2. For each title, right-click on the movie (the movie loaded on the preview screen in MyDVD) and select the Show settings option.
3. Select on the Starts at pull-down list and re-select Chapter 1 on each movie added to the screen.
4. Burn the DVD.
I un-installed version 9 and then installed version 10. The reinstalled version 10 again. I installed version 9 but now I get a certificate file is missing. I think things a hosed up now due to the uninstall and reinstall. I have XP media center. Is there a tool that will clean the 9 and 10 out so I can reinstall?
