Hi Margaret, It means there are missing files in the VIDEO_TS folder on your hard-drive There is not much you can do from here apart from re-author/encode your project again from PhotoVidShow. Assume this is not a problem.
If you burnt the DVD previous, you should be able to rip this DVD onto your hard-drive to create another VIDEO_TS folder. This is the same as just copying the DVD, photovidshow does not create protected DVDs, so using any DVD copying software is perfectly legal.
Ok i see, yes often the DVD software that comes bundled with the burner hardware will do simple DVD copying (non protective)
If not www.magicdvdripper.com/ allows you to copy and also rip back onto hard-drive as VIDEO_TS folder. I think the free trial version allows you to Rip 4-5 times before the trial runs out, which maybe all you need.
