Suggestions on backing up old self written DVDs
Posted: Tue Feb 24, 2026 7:21 am
Hi I'm brand new to MakeMKV and the forums but I failed to find anyone talking about my issue. About 18 years ago I converted my family's old home movies into DVDs and burned them onto 4 DVD+R DL discs. It's on me to have lost the original ISOs since doing this but now I'm trying to protect the memories better by ripping them all to ISO to preserve my menus. I'm having problems with 2 of the discs getting the exact same output:
The discs aren't 100% pristine, but they're so very barely scratched. I strongly suspect the problem is just the DVD layer chemistry itself degrading over time. Still, I've tried lightly polishing with a microfiber and also tried both discs on 2 separate drives.
Both discs play in a player just fine (or so I can tell) and both rip to ISO with DVD Decrypter which MakeMKV then turns into MKV files just fine. I'm a little worried that there's some corruption getting preserved and I just haven't found it yet, or am I just worried about nothing since the output of what I'm trying to do seems to be just fine? Does anyone have any other suggestions I should try?
