Select 'Copy DVD_Video...' . This just excludes other files that may be on the disc outside of the VIDEO_TS folder. If you select '..original IFOs', some protections will not be removed, so skip that. Clone mode will still have all the previews, warnings and other crap that they put on discs. To my thinking a Main Movie ISO is a better option and is much smaller. But if the disc has extras or features you want to be able to select, use Clone or Full Disc to ISO. For TV series DVDs, consider using Customize mode, which will allow you to preserve the disc menus and copy all the episodes and worthwhile extras but exclude previews and FBI warnings (if you are willing to take the time to find them using the Preview function).
