ripping errors (dodgy disk?)

[DalienX]

hello all.
Am trying to backup stargate atlantis but im stuck on one of the disks.
I usualy use dvd decrypter but it fails at 96%.
After spending an hour or so reading other threads in here i have just tried dvdfab6 and anyDVD but they all failed to rip the disk.
Yet the disk plays just fine and has only a few light scratches on it.
Any ideas?
Or do i have to buy another copy :(

Maybe not buy another copy, but possibly an exchange. However, you say that it plays just fine. Maybe the error is on some special features. Try just ripping the main movie / episodes. You may be able to essentially "rip around" the error spot.

I always give this advice: use an LG DVD burner, to my experience they have the best reading capabilities in terms of scratched discs. If possible, find a lower speed one (4x, 8x).

I would say that you have a bad disc. I had no problem ripping any SG Atlantis using DVD Decryptor.
