I have had no luck whatsoever copying DVDs made in any standalone settop recorder (i've tried several). I've tried different media brands, different media types. I've finalized all of the discs before attempting to copy. This should work. Everything else in the world will read these discs correctly except CloneDVD. Whenever CloneDVD sees one of these DVDs, It tries to "repair the dvd structure"...only thing is, there's nothing wrong with it. I understand CloneCD can be used to COPY, but if I want to edit or remove chapters, etc...I have to use CloneDVD...therein lies the problem. Anyone know why this happens? Is there a fix?
