You dont need dvd shrink if you have nero 7. Dvd shrink was written by the same person that originally wrote nero recode and they are very similar programs (they do the same thing) though I’m guessing nero has had a little more put into it as it is pay software. Shrink is popular as it is the best free software.
Put your dvd that you are copying in the drive.
start dvd decryptor. It should find the dvd on its own (the drive that has the movie should come up in the source and several files wil apear in the right window (all files will be selected, if they are not, select them). If the source is wrong, change it to the drive where you have your movie.
The destination should be something like c:\starwars\video_ts where starwars will be replaced with the name of your movie. Remember this location.
click the button that looks like a disk/arrow/drive
it will run and rip the movie to your hard drive, removing copy protection, when done, close dvd decryptor.
start nero startsmart, and find the copy entire dvd-video icon and click it.
Click import dvd and find the video_ts folder that dvd decryptor created on your hard drive (not the one on the actual disk, the one on the hard drive) and click ok. It should run through a quick analysis.
Make sure dvd-5 is selected as the fit to target size for a single layer blank disk.
click next till you get to the last screen where it lets you select the destination. Insert a blank dvd and select the burner as the destination, and select burn speed.
Click burn. It will take a little while to encode, and then it will burn it. That should be it.
Be aware, dvd decryptor is no longer updated. It will do most movies but not some of the newer ones as they have more advanced copy protection. If dvd decryptor fails, consider ripit4me or dvd fab decryptor (free) or anydvd to get past the copy guard. The first two will copy like dvd decryptor. Anydvd will do that or just let you use the original disk as the source in nero because it runs in the background and removes the protection (there will be a video_ts folder on the actual original dvd).
Hope that helps.
