Read error help please

[Techoverload]

Trying to rip two DVD's my in-laws had made several years ago. They took/sent (not sure if it was local or a mail in service) a bunch of old family film movies and some photos from the 50-60s to a service. They got two DVD's back. As I know DVD's can have issues with degrading/stop working, especially non commercial "burned" discs I wanted to back them up onto a external hard drive. Am also planning on converting to MP4 so I can upload them as private videos to youtube. (Any suggestions on software to do that also accepted).

Anyways......one of the discs ripped fine. The other one gives constant errors at one spot.

Code: Select all

Failed to save title 0 to file C:/Video/My Movie/New folder/My Movie-A1_t00.mkv
Encountered 17 errors of type 'Read Error' - see http://www.makemkv.com/errors/dvdread/
0 titles saved, 1 failed 

I have cleaned the disc and it doesn't appear to have any scratches etc. Have tried 4 times and it always fails with the same offset '1005598720'

Disc seems to play fine if I just watch it using the standard windows app.

Any suggestions?

It can play fine and still fail in MakeMKV. Certainly seems like the drive is having a problem reading that disk, i.e. hardware error causing MakeMKV to fail.

What I would do in this situation, is make an image of the disk (ignoring errors) and use VLC to play the ISO. That way you have a digital copy is some form. I do this under Linux with ddrescue. Note, for some disks this can take up to a week (!!) or more to complete. With a map file though, the copy can be halted and continued as needed. I see there is a windows version ddrescue-gui that can be purchased. I have not tried it. ImgBurn has an option to ignore read errors, it might also work. Again I haven't tried it. I've also found that makemkv can sometimes work on the image that's made. It still produces errors but gets past them to make a MKV. You may notice artifacts in the part of the video where the read errors are.

To do this successfully, I run makemkv first to open the disk. This puts the drive in Libredrive mode and "caches" the CSS key(s). Then I run the imager software without taking the disk out of the drive. If you start getting a lot of read errors right away, you are probably trying to read a drive without the CSS key loaded.
