I already did some research, and tried the Handbrake program. The audio comes out ok on it, but the video part is all screwed up and won't go on my ipod. I followed a few different guides online and it still didn't work.

Are there any other free programs that are EASY to use to rip the DVD's? I don't want to pay for movies that I already own to put on my ipod.

I have an HP and Windows Vista, if that helps at all.
