incorrect parameter

[kindred59]

Hi Everyone;

I'm trying to copy a copy, and while parsing, I get an i/o error stating incorrect parameter. It happens with any software that I try to use, dvd decrypter, dvdfab, etc.. I was wondering if anyone can help me with this problem?

Hi!

Probably a poor quality copy (either poor media or poor burning).

Simply make another backup from your original, commercial DVD...
