I am new to this so hopefully I am not asking a stupid question. I am trying to backup a DVD using DVD decrypter and DVD X Copy platinium. Neither have worked. Everything is going fine until the programs get about half way throught the disk and the programs slows down and eventually errors out reporting sector read errors. It is interesting because I am backing up a mutliple disc TV series. I have been able to backup every other disc from the series, but two. I have two computers and both have the same problem. I checked for scratches on the DVD's but there were none. The discs play fine in the DVD player, but seem to have problems playing on both computers using WinDVD 4.0. I have spent hours reading the manuals and I have not found any solution. Is it something simple I am missing? Any suggestions?
