New HTPC, what software do I need to put videos on HDDs?

Hello all, I recently completed a basic HTPC for my living room TV and I want to put my DVD collection on my HDDs so I can view them without using the Discs. Along with the nearly 200 DVDs I own, I own some BluRay videos as well, is there a software that will put the video image of both DVD and Bluray on the HDDs? What is the best software to do this? I don't mind buying it but I prefer some freeware if it gets the job done.

Thanks

We can't really talk about duplication of copyrighted movies here, I'm sure you understand why, but you have a private message.

I do understand. Thanks
