Cloning DVD with bad sectors?

[chisdchisdq]

Hi, I'm trying to copy a DVD to a iso file with DVD Decrypter , but it shows many read error starting form about 8%. It had not finish copying after over 3 days, even I set Read error reties to 0 times. Since there are no obvious scratches on the DVD surface, and the playback of the discs seems normal, I suspicious that it was having bad sector protection. How can I clone it faster by skipping all bad sectors?

Check hardware retries too. I don't remember what it means in DVD Decrypter, but be careful, sometimes 0 means infinite not zero. I would set both to 1 to be sure.

Try IFO and File mode instead of ISO.

Also Try DVDFab. The DVD ripping feature is free and it's much more up to date with different obfuscation schemes.
