You are probably trying to do a movie with the newer protection that Shrink cannot handle. Get the free ripper DVDFabDecrypter and rip to your HDD and the proceed with Shrink.
Some of the new movie releases are copy protected by either sony's or microvision's encryption, that means shrink or DVD Decrypter will not be able to decrypt these movies because they're no longer updated to do so.
Shrink is producing this error:
Quote:DVD Shrink encountered an error and cannot continue.
Invalid DVD navigation structure.
because of copy protection it can't handle, so it's going to need a little help. If you want to be able to backup these problem movies for free and are not afraid to do a little work doing so..then follow the instructions below for all movies that shrink or DVD Decrypter can't handle.
Here's how to get it done For FREE: **************************
Download and install DVDFab decrypter (make sure it's the latest version), use DVDFab to rip the video files to your HDD.
Once DVDFab decrypter is done, you'll have a VIDEO_TS folder on your hard drive containing the files it ripped. These files will need to be processed thru vobblanker to remove fake cells and correct file structure so shrink can open the files and process them correctly.
Unzip the file and run the executable, it will look a bit like this:
For input folder selection: browse to where the VIDEO_TS folder created by DVDFab decrypter is located, inside the folder, look for the VIDEO_TS.IFO file and choose it.
The path might look something like this:
c:\Movie folder\VIDEO_TS\VIDEO_TS.IFO
Note: When importing the VIDEO_TS.IFO file, if you notice that vobblanker has marked a video title set (VTS) in the top half as skipped, click on the Proc.All button on the right to ensure all video title sets are processed.
For output folder selection: create a new folder on your desktop and call it "MOVIE", inside that folder create a new folder and call it "VIDEO_TS "(this is where you'll have vobblanker put the output files it will create)
Once the folders have been created, have the output folder selection point to the VIDEO_TS folder in the MOVIE folder.
The path for output folder might look something like this:
c:\documents and settings\johnl123\desktop\MOVIE\VIDEO_TS
Now just press the PROCESS button on the bottom and wait until it's done. Once the process is complete, there should be a new set of video files that vobblanker created in the VIDEO_TS folder that's in the MOVIE folder on your desktop.
At this point run DVDshrink and open the files, click on the "open files" tab and browse to where the VIDEO_TS folder is that's in the MOVIE folder on your desktop and choose it. Shrink will import the files now correctly with no errors, at this point you can use shrink as you normally would to create a backup. Have shrink reauthor the DVD to backup just the main movie and 5.1 eng audio channel, have shrink create an ISO image and burn it to disk using DVD Decrypter.
