I got a DVD, never used with cellophane intact, produced in 1993 on ebay. I thought maybe, since I didn’t get a DRM warning, it predated DRM, and I could just copy it to my hard drive, so I did. Both the copy and the DVD are now corrupted and unplayable. I want to fix the DVD then rip it to my hard drive. Googling gives plenty of suggestions for ripping but none for fixing. Please help if you can. Thanks.
Maybe you can try DVDFab DVD Copy, which may recognize your corrupted DVDs and make a backup copy of it. This tool is good at decrypting and coping old DVD.
