Software for recovering a defective DVD

[base689]

I have DVD's that I have burned years ago and once put back in playback, at a certain stage it stops because defects on DVD surface (which are NOT scratches). It stops when paying it back both on PC DVD burner and on a stand alone DVD player.
Such defective DVD's are not copyrighted, they have been burned from other people from videocamera tapes.
I perfectly know that it is very likely that I used crappy media, now I am using good quality media, but nonetheless I would like so much to recove those data.
I have already used Isobuster with the "replace with balnk defective data" option, it took a lifetimwe (like 12 h or so) to recover a single 1 GB VOB file onto HD, but once I tried to burn a ned DVD using all the VOB files (including the recovered one) both CloneDVD and Nero told me that thay could not read the source file(s).
UI understand that Isobuster deals with "data" and when it is impossible to read few sector, it simply substitute them with blank data.
I guess that even if Isobuster recreates a whole of data compatible with "data DVD" structure, once a DVD authoring/burning software comes to read data from HD and discover these data are NOT coherent with video/audio frame structure of a DVD/video file, it stops.
To make short a long story: does it exist a software that UNDERSTAND it is dealing with a video DVD so that, once it encounters defective sectors, it simply substituts them with "blank data compatible with video DVD structure", so that in the end it discards few frames (possibly in a way to get NOT noticed by human watching DVD playing back)?
Does it exist a software capable of recovering defective "video DVD" onto HD?
Thanks

Maybe try cdroller.

I had the same problem with one disc, and Isobuster didn't help. Then I decided to try ripping the bad DVD with DVDFabHDDecrypter, and it actually worked. It seems to be very forgiving of disc errors. I know it wasn't made for that purpose, but it worked for me. In my case, it may have been a fluke, but you might just want to try it out yourself.

Agree with filmboss80, try DVDFab HD Decrypter > FixVTS>Shrink.....

It may be usefull for this thread as well (it does not recover lost data but it's a nice method to easily get the uncorrupted MPEGS from a corrupted disc):

I just found a way that works very nice. I still had an old version of Ulead DVD MovieFactory/Disc Creator.
It has a feature called "Edit DVD". When you start that option it will start to extract the titles as separate MPEGs from the DVD. If the VOB contains an unrecoverable error it will just end the video on that position and continue with the next VOB. Run the program, start the edit disk option and when the DVD is captured go to the scratch disk folder and copy the mpegs somewehere else (if you close the Ulead program it will also automatically delete the mpegs).
