Because DVDshrink is no longer updated, it can't handle the new sony or microvision copy protection being placed on some of the new movie releases, this can cause it to stop encoding, shut down, or produce an error condition. DVD shrink can't handle some movies alone so.....
Keeping it FREE by using free apps: To get around this you could try a very good ripper/decrypter called DVDFab decrypter, it'a a whole movie ripper so you'll still need DVDshrink to reauthor the DVD if you want to remove any unwanted extras and shrink the files to fit onto a single layer DVD.Once DVDFab is done ripping, open the files using DVDshrink's open files tab and proceed using DVDshrink as usual.
Note: You might not need to do this with the current version of DVDFab, but.... If DVDshrink won't open the files ripped by DVDFab then you'll need to process them thru VobBlanker first (vobblanker will produce another set of files, put the files produced by vobblanker in another folder on you desktop and call it VIDEO_TS), once vobblanker is done open the files it produced using DVDshrink as described above.

If you're curious???
The easiest way to get around the copy protection is to purchase Anydvd, it's a driver that runs in the backround helping DVDshrink crack the copy protection and produce a backup. It comes with a 21 day free trial, check it out here:
