I'm trying to make some copies of a friends scratched DVDR which appears to be partly corrupted as it "freezes" in a couple of places on playback. I've tried doing a straight transfer using a Wytron DVD 399 tower system, but it always fails before completion. I then tried using DVD shrink, DVD Decrypter, and DVD Fab decrypter, all of which fail.
If I could open the disc and copy all the files across and burn a new DVD, that might work. I've been able to copy all the files except for one of the VOB files, which gives the error message "Data error (cyclic redundancy check)"
My final idea was to use a DVD cleaning kit from Maplins, which polishes the DVD with slightly abrasive pads to remove the scratches, rather like T-Cutting a cars' paintwork. I've now done this 20 times (!) which translates to 3 hours of cleaning / polishing and the scratches are now virtually invisible, but I still can't extract the final elusive VOB file.
If I could extract it, even with its possible errors, and burn to a new DVD that would be fine as most of the material on it plays OK, but so far I've been unable to make a new DVD capable of being copied.
Does anyone know of software that performs powerful error correction, rather like the excellent "Exact Audio" software that does this on CDRs, or can anyone suggest any other ideas, please?
sounds like your DVD is scratched or damaged beyond repair! Is this a copy of a DVD or is it the original store bought DVD..... if it's a store bought DVD..... try to return the DVD to the store and get another copy!
If the VOB file is that damaged (and if it's too late to return it) then I'd think the best thing would be to re-author a DVD from scratch, creating new IFO and BUP files.
If you have DVD Decyrpter set to "ignore read errors" you should be able to get the damaged VOB file copied to your hard drive, it might take a while though.
Then I'd open the damaged VOB file in an editor like VideoRedo and cut out the damaged section. You might also run VideoRedo's Quick Stream Fix to clean up the timings.
Then using the good VOB files, and the repaired VOB file, use IFOEdit to author a new DVD.
