Did you rip ALL files in original format to your HD ?
Is the folder 'VIDEO_TS' existing, and is it uppercase ?

Have you used 'Get VTS Sectors' on all IFO files, right before burning it to DVD-R ?
Have you re-started IfoEdit before you've used 'Get VTS Sectors' ?
Have you created an image with IfoEdit's image creation button ?
