I just started backing up dvd's i buy, I've been using "dvd decrypter" and nero to back them up. all as been well until recently. Whenever I back them up, I only add the main title to copy, no menu's or extras. Some of the latest movies I've tried, are blank in the start for quite awhile, then the movie starts playing fine. Even in the nero preview before the burn it takes quite awhile for the movie to start. I'm not really sure how to fix this, so any help would be greatly appreciated. I'm a noob so dummy instructions if you got em.
