I am trying to convert a film for dvd with instant CoPy 8.251 (dvd-9 to dvd-5). I make the process all normally but when it is almost finishing to convert the film the computer reboot without any reason.

I ripped the full dvd files with dvddecrypt, when I try to preview the main movie in IC 8 I get the error: "Corrupted DVD Source". The extras and copyright movies are normal. With Shirink, Clone DVD, I don't have any problems.

What's happening? Any help??
