I know there should be editing software that will extract from a DVD, but I don't know what it is. I have handled this 2 different ways.Â
1. I have some software called DVDfab that will copy, extract, convert any DVD to an Mpeg file, IPOD format, PSP, etc. That is one way to extract. http://www.dvdfab.com
2. Another, rather low tech and easy way is to play the disk in a DVD player and run RCA cables out to your camcorder, record on the camcorder while the DVD is playing, and then capture from your camcorder back into your PC. I know there should be some loss with this, but I can't really detect it.Â
I hope someone has a better answer for you, because I'm curious as well.
Good Luck,
Trey
