I've tried to rip a dvd with smartripper in my laptop pc ( with WinXP ). It happens that when it reaches the 8% of the work it blocks. I have tried with others programs (cladDVDXP13) and it boloks himself at the same point. So I have tried in my desktop pc and it works. Anyone knows something about? The autentication procedure works, and the ripping starts. I do not change parameters. Help me!!! Maybe it's about the XP? Help!
