DVD ripping software that can ignore read errors? *SOLVED*

BrionS · Last edited by BrionS on Sat Nov 17, 2025 4:11 pm; edited 1 time in total

Does anyone know of DVD ripping software that has the ability to ignore bad sectors / read errors?

The reason I ask is because I'm trying to backup my Underworld Evolution disc but Sony's copy protection includes a bunch of bad sectors scattered throughout the disc that - from what I read - need to be ignored (and replaced on disc with dummy sectors).

I've tried all the following with no luck:

vobcopy
transcode
mencoder
dvd::rip
ogmrip

None of them seem to be able to handle bad sectors. Sad

Assuming nothing exists, does anyone know where I can start learning the ins and outs of DVDs to go write a patch for transcode or mencoder to allow the replacement of bad sectors with dummy sectors? Smile

Thanks!
Brion

I tried it with our Memoirs of a Geisha DVD, and had a similar problem. I even went over to the dark side (aka Windoze) and tried DVD Decrypter and that didn't work either. Neutral

I ended up going to a filesharing site to download a FRICKIN MOVIE THAT I ALREADY "OWN."

Note: own is in quotes because you still don't own it, even though you shelled out $10-$20 for it. If we owned it, we could do whatever we wanted with it.

I know its a windows app but you can use a program called DVDFab to decrypt Sony's copy protection. There is a trial version available but I haven't got the link to hand at the moment.

Ooh...I forgot about Wine (or Crossover Office). Perhaps I'll download and try DVDFab with that.

I know there are a bunch of Windows apps that can do it in a series of steps, but I haven't even found one Linux DVD ripper that lets you "ignore read errors" or skip bad sectors.

Thanks....I'll have to try that later. (Headin' out to see Pirates of the Carribbean: Dead Man's Chest tonight, so may not have time to try right now.)

Unfortunately DVD Shrink won't work with Memoirs of a Geisha. It bails, too. Sad

DVD Decrypter will not work with the later type DVD encryptions used on the more recent disks. you have use something like DVDFab.

Maybe if you used DD_Rescue (there's a thread about it on here somewhere) and just told it to NULL-pad the bad sectors. Then pointed whatever tool at that image rather than using /dev/hdc or whatever.
