title missing ~30 secs, won't rip past it

[DynVec]

A title I'm most interested in is missing about 30 seconds using VLC and the DVD. As most of my DVD rips, I do it using Handbrake. This title failed so I tried dumping it on HDD using DVDfab > DVD Copy > Customize, I selected the track in question. There was soon error so, as with erroneous files, I selection Ignore All ; it finished like normal so I used Handbrake on that dump directory trying to make the target (compressed) file. All seemed well so far but the length was ~1/3 of the DVD one. I then played the DVD trying to get as close to the time of the previous file which got pretty close, then VLC stopped. Then getting close to the time I skipped 1 min and it played so I backtracked until it stopped again ; calculating the unreadable gap.

Is there a program that would seek longer than DVDfab obviously don't go? Or is there a way to manually set the beginning of a rip, so I'd then join the 2 parts?

Thanks!

what is the dvd stratched or cracked? have you tried warm water and soap to clean it if it's just dirty?

[DynVec]

There are scratches deeper than I'd like and there's a somewhat large patch of discoloration, like there was a bubble between the protective & data surfaces. But, as the title mention, it's only ~30 secs, so I'm doubtful it's that patch.

i'd rip the dvd up to the defect with dvdshrink in re-author mode, and then start after the scratch and rip to the end.

You can use DGIndex to create an index file for an AviSynth script if you're reencoding it. It'll probably result in big colorful blocky gibberish video during the corrupted part. You can either encode that or cut it out or replace it with the last good frame or whatever you like. The audio is probably bad at that point also.

I installed dvdshrink then put the DVD in. I don't understand Re-author mode but I wanted to give it a try still ; so I was in the mode but couldn't find a way to load the DVD in that way. So I went into Full Disc then 2 icons became enabled: Open Disc & Open Files. I opened the disk then an analyzing window popped up, some images scrolled and the % increased and at some point there was an error. Well I don't know what to do now.

it seems you were writing me while I was replying (to aedipuss). I don't understand so much what you wrote me but I'll fiddle a bit with the programs and see what I can do. I'll let you know if I'm at a hurdle.

Try IsoBuster. Could take a long time, depending on the damage. No guarantees though.

Try DVD Decrypter with the Ignore Read Errors option enabled. You'll also want to reduce the Software Read Error Retries count to a low number. Like 1. It may take a very long time to rip a damaged disc because the drive firmware automatically attempts many retries when errors are encountered. And, of course, the resulting VOB files will be corrupt where those read errors occurred. But you may find tools that can skip over the damaged sections.

I thought he already got it decrypted to the hard drive:

...I tried dumping it on HDD using DVDfab > DVD Copy > Customize, I selected the track in question. There was soon error so, as with erroneous files, I selection Ignore All ; it finished like normal...

or did I just misunderstand (again)?

I wasn't sure exactly what DVD Fab does when it encounters read errors. So I was offering an alternative.

In Isobuster I right-clicked on the optical drive then chose Extract DVD <Content> then the only enabled option Extract User Data ; there was also the option Extract DVD <Image> but I thought the one I chose was closest to what I'm used on DVDfab when Handbrake give me trouble: DVD Copy. At some point it alerted of an unreadable sector and it gave selections beside the usual retry & quit: omit sector skip, replace with all zeros & replace with dummy data ; I chose the 1st option after checking always apply selection.

So it seemed to do good, it took hours to get through the DVD. It produced an .iso file which I opened with Handbrake but it gave me even less option than directly on the DVD. So I tried to first extract the .iso before having handbrake open its content folder but I had some errors, see attached, which state: Data error in 'FILE_NAME'. File is broken on extensions: bup, vob & ifo.

So I still can't get past the error, I'd just like to have a program which could start ripping 1 minute after the error ; a software which I could specify the starting time of a title. Then I'd merge the resulting file with what I already got (stopping at error).

Well I can't figure out how the suggested course of action apply to my problem. I opened DGIndex and in the menu File the only of the few enabled option is load and the default filter is All MPEG Files and the others are seemingly ripped content. To what I determine, my problem is the actual ripping, not the processing of the ripped data.

If you have more than 1 dvd drive try dvd image and create a managed ibq or ibp file. Run the disc in one drive and if it can't complete the extraction use the second drive in conjunction with the ibq file. The help documentation in IsoBuster should explain.

I was under the impression, based on my earlier post where I quoted you, that the DVD decrypting was complete and it was on the hard drive and OK except for the 30 seconds of corruption in it. I guess I was mistaken. Anyway, if you don't know enough to load only the movie VOB files into DGIndex (rather than menu or other useless VOBs, or the IFOs and BUPs), it's not going to be of much help to you.
