I’m using dvd fab plat. And I copied one movie and it was Ok ,but the second movie I copied didn’t copy all of it,This was a different movie. The last part is missing. Is there something I’m doing wrong. It was someone else copy. The movie is all there because I watch it. Thanks… Also is there a tutorial on DVD Fab. Thanks Again.
