I'm looking for the best software, free or not free, that will make the best copies from DVD to AVI. I don't mind paying money because making AVI copies will save my disks from the kids scratching or misplacing them. While I haven't stepped things up to bluray yet, I wouldn't mind software suggestions that can incorporate bluray to AVI as well, incase I upgrade my diskdrive to a bluray playback model.

I don't want to make copies of my disks to blank disks, because I'm looking to just play videos off of my HTPC and avoid extra disks all together.
