I need a good DVD decryption program

[Bones]

I have looked around for something to help me back-up my out of print dvds, but everyone wants from 50 to 100 dollars for the software to do so. AnyDVD and DVDfab look good but I would rather not have to keep ponying up money just to get my stuff backed up to ISOs

 

[strawman]

I use DVDDecrypter. It's old and not updated recently (due to legal issues) but it's free, and will decode and rip straight to ISO with no fuss.

^ this.

If you want to rip the movies and are not anal about encoding Handbrake works great (at least on OS X it does).
