My hard drive crashed and I lost some of the edited avi files. I still have the original tapes and some of the raw captures on dvd data discs. But in order to reedit them, I need to rip some of my dvds since those have the videos in their final edited form. I'm not looking to edit the ripped video much, just mainly as a guide to match things up. And since they're from my dvd's, I don't have to worry about copy protection but I might want to rip copy protected video at some point later on.

What program (free if possible) would you reccomend? I've heard about something in a videohelp guide called I think dvd decryptor. Is that a good choice?
