Error message when trying to read ISO files from a DVD disc

[Edda]

Hello there. In my attempt to read an ISO-file with DVD decrypter (am backing up all my old and scraped DVD's) I stumbled upon this error message after 7% completed:

(!)W 02:26:02 Inserting Dummy Sectors... (LBA: 301616 - 301976)
I 02:26:02 Extracting Sectors...
(!)W 02:26:02 Sector 302086 - Pack Header Not Found (0x00000000)
(!)W 02:26:02 Sector 302087 - Pack Header Not Found (0x00000000)
(!)W 02:26:02 Sector 302088 - Pack Header Not Found (0x00000000)


And so forth. I've never encountered this problem before with DVD decrypter. Could it be some kind of copy-protection or is it something wrong with the DVD? I'd really appreciate any tips on what I could do to correct this.

EEDIT: The film is called "The constant gardener" btw, if that is any help.

Thanks in advance

The Constant Gardener, R1 version, contained no special copy protection scheme. Make sure you're running the last version of Decrypter. If that fails you, you might try running it through DVDFab Decrypter. Here's a thread on The Constant Gardener.

You can also come up with some ideas using "pack header not found", both inside and outside the Forum.

Thanks ammck, it worked like a charm! I managed to copy the entire disc with DVDfab Decrypter without any problems. I then shrunk it in DVDshrink and burned the ISO-file to a DVD-R. The disc works perfectly now!
