Planet Earth as You've never seen it before The Complete Series

[csdonnell]

I am trying to backup up this dvd collection. It comes with 5 disks. Each disk has 3 titles on it. Makemkv only creates 1 file with only the first file on each disk. The errors I get are below. I've tried several dvd and blu ray drives all with the same result. I can send output from my lg blu ray player as well if that will help but basically the same errors. Any ideas? Thanks.

Above post is using my lg blu ray drive and CellFull

Is it not possible to backup this series?

It looks like both drives show an error trying to read the disc at a similar spot. The standard advice is to try cleaning the disc.

[csdonnell]

The problem with that theory is it happens on all 5 disks and they look clean to me.

[dcoke22]

Based on the errors you've posted, the optical drive can not properly read a spot on the disc. That isn't a theory.

Do the other discs fail in a different way?

That the discs look clean doesn't mean it is clean. One can not see the individual pits and bumps that make up the data track on the disc so it stands to reason that a contaminant too small to see might interfere with the laser's interaction with the disc.

In the end, it might be out of your control. In my experience, some drives just don't like some discs. I have four drives and my main drives reads most discs most of the time. But when it runs into trouble with a disc almost always one of my other drives will read it seemingly without any trouble at all. Very rarely I end up with a disc that I have to replace and in that handful of cases my replacement copy has worked fine.

Hmmm I've tried two drives and all 5 disks. I will pick a disk and record the output from both drives and post here.

This also happens with the Blue Planet disks. I don't have an issue with any other disks on these drives. I understand it could be a bad disk but between the 2 series there are 10 disks which seems unlikely its a disk issue. I will post a more detailed review of both series and using different disk drives and disks.

Here is the other series Blue Planet. This is my dvd drive.
