Ok my question is this. Say I make a backup and then make a copy of a movie I own using shrink and nero, but then for some reason my original dvd was scratched or damaged. WOuld I be able to make an exact copy of my already compressed/encoded dvd??(my copy) Or would it lose further quality? Oh, and would I have to analyze and recode all the information all over again?(if I used deep analysis and some of the other enhancements) Sorry. I am very new to this whole thing, any reply's would be greatly appreciated.
For that, I just use DVDDecrypter and make an ISO copy. Basically a 1 to 1 copy of the copy. DVD Clone does it now too.
Put in the copy, select ISO Read, read the disc, put the image onto your HDD, put in the blank and then hit ISO Write, selecting the file you just put on your HDD.
Just use it's DVD-Copy application to make a disk to disk copy. It will create an image from the original/copy and cache it to a location on your hard drive, when its done it will ask for a blank disk, insert one and let it do its thing (keep the write speed at 1/2 the rated speed of the media).
If your trying to make a copy of a copy and are having problems doing it, this is how I get it done without ever having a problem.
How to Make a Copy of a Copy Using Nero
You successfully backed up a DVD, do you need to use DVD Shrink again to copy the already copied DVD? Nope, Nero allows you to make a identical copy of the already decrypted copied DVD. Insert the DVD your trying to make a copy of in your DVD-ROM +/-R /RW drive and let it be recognized.
1. Run the nero burning rom application from the smart start menu under application. The wizard screen should pop up on top of the main Nero screen. On the left hand side, you may need to tell Nero if your making a "CD" or a "DVD" copy. Of course you would be making a "DVD" copy, so simply click the down arrow and select "DVD" as your choice. (Illustrated in the screen shot with the red arrow.) Screen Shot Below:
2. After you have selected "DVD" as your preferred compilation type, now click the "DVD Copy" icon. (Illustrated by the blue arrow.) Screen Shot Below:
3. Now for configuring the tabs at the top. There should be 4 tabs at the top. "Image", "Copy Options", "Read Options", and "Burn". I will take screen shots for some of the tabs instead of explaining each one completely.
4. The first tab, is the "Image" tab. See Nero makes a image of the burning process and what files are attached to it. Then you simply load that image into Nero and burn it. (Nero does it automatically if you are using "DVD Copy" compilation.) On the "Image" tab, the first box is the "image file" box. This is where you want Nero to save your "Image". ( I always save my image to the desktop, cause I delete it right after I burn the copy of the copy.) Click the "Browse" button to the right of that box, to choose the destination for the image. (Whether it be on your desktop, in your "My Documents"folder, where ever.)
5. Below that box is box to put a check mark in if you want Nero to automatically delete the image after it has successfully burned the image to disk.
6. The "Hard drive speed info" is next on that tab. I don't know what it is, so I don't even bother messing/changing it.
7. The next tab is the "Copy Options" tab. Here you can select how you want Nero to copy. Although burning with the "On the fly" option is faster, it is not recommended. Next option to change on the "Copy Options" tab is selecting your source drive. (The drive with the original copy.) Then under that is the "Read Speed:". You can select what you want here. I have mine set at "3x (4,155 KB/s)" to eliminate possible read errors from reading to fast.
8. The next tab is "Read Options". (Just going to post a screen shot of mine) Screen Shot Below:
9. The next tab is the "Burn" tab. (Again I'm just going to post a screen shot of mine.) Screen Shot Below:
10. Instead of maximum, set the write speed to 4x, 6x, or 8x (try to set it at no greater than 1/2 the rated speed of the media), click burn and your done!
Note: If you have only one combo drive, nero will prompt you for blank media when it finishes caching the image before the actual burning process can begin.
